+	  them with select() like child process
+	- alarm()/SIGALRM usage removed and replaced with counters and

+	- ***NOTICE*** the format of conserver.cf and conserver.passwd
+	  has completely changed.  see the INSTALL file for
+	  upgrade instructions (it should be "fairly painless").
+	  some documentation has been updated to reflect the new world,
+	  some hasn't - my goal for beta2 is to have all the docs updated
+	- many command-line options now also conserver.cf options options
+	- POSIX termios interface now required for compilation - some

+	  undoubtedly creep in as time goes by
+	- configure --with-regex option removed because of conserver.cf
+	  and conserver.passwd changes

+	  every minute like the manpage says it does - reported by Chris
+	  Fowler <cfowler@outpostsentinel.com>
+	- when -R option is used, substring matches on console names
+	  from clients only match local console names (and if that
+	  fails just remote console names) but ambiguous name list

+10) Is there a technical reason why --with-maxmemb's default is 16?
+    I've changed mine to 96.
+
+    The following is an array of things you need to think about when
+    adjusting --with-maxmemb.  It's a bit long, but it's an important
+    question.
+
+    The big reason (and the main reason for conserver spawning multiple
+    processes) is the maximum number of open files a process can have.
+    Each console can have a few file descriptors associated with it
+    (device, logfile, connected users, and listening socket).  So, each
+    process will have about ( 2 * consoles + users + 1 ) open files
+    (--with-maxmemb sets the maximum number of consoles per process
+    in the equation).  Although most current operating systems allow a
+    large number of open files per process, the general assumption is
+    it's still pretty low.
+
+    You also have the speed of your conserver host vs the rates at which
+    data could be streaming to it.  Go back a decade and this was probably
+    more of an issue than today, but it's still something to think about.
+
+    And then you have the problem of delays.  If any of the 96 console
+    connections "lock up", it'll delay all activity on the 96 consoles.
+    With 16, there's less of an impact.  This can be an issue once the
+    server is up or during startup.  Also, with 16 consoles per process,
+    you get a bit more parallelization during startup.
+
+    So, is there any reason not to up the number to 96?  No.  Assuming you
+    know the risks and weigh things appropriately.  If I remember right,
+    I've upped the number to 48 at some sites.  But that was mainly to
+    reduce the memory footprint in older versions of the code which had
+    statically allocated buffers.  No need to worry about that with the
+    current code.  Personally, I wouldn't change from 16 unless there
+    was a really good reason (like wanting to only have one child process
+    for firewall rules or some such reason).
+
+99) OK, things just don't seem to work.  Help?!?
 
     Yes, this is a pretty vague question, but here are a few tips that
     might help.

 Upgrading?
 
@@ -10,42 +10,125 @@ Upgrading?
     new features added to the client if you're considering *not*
     upgrading.
 
+    Version 8.1.3
+	- The '^Ec;' sequence won't work correctly with 8.1.2 (where it
+	  was introduced).
+
+    Version 8.1.2
+	- The 'devicesubst' and 'execsubst' formats have changed from
+	  8.1.1.  It's fairly simple to update your config file to the
+	  new format...just check the conserver.cf manpage.  Sorry for
+	  having to change things, but it's for a good reason (I should
+	  have though ahead when designing the original format).
+
+    Version 8.1.0
+
+	- The client/server protocol has changed to better protect 8-bit
+	  data and to allow programs invoked with '^Ec|' not have to
+	  worry about accidentally sending the escape sequence to the
+	  server.  Though it will look like things are mostly
+	  backward-compatible, don't count on it and just upgrade.
+
+    Version 8.0.2
+
+	- I've added a '^Ec;' sequence to allow the client to signal the
+	  server as to when it's ready to see console data.  Without
+	  this, verbose consoles will prevent clients from attaching
+	  (the client sees unexpected data).  An 8.0.2 client should be
+	  compatible with an 8.0.1 server, but an 8.0.1 client is not
+	  compatible with an 8.0.2 server.
+
+    Version 8.0.1
+
+	- There's a slight client/server protocol change to implement
+	  the new 'initcmd' console option.  If you use this
+	  functionality with an 8.0.0 client, you'll run into a
+	  compatibility problem while the 'initcmd' command is running.
+
+    Version 8.0.0
+
+	- The client/server protocol has been rearchitected.  You *MUST*
+	  use an 8.0.0 client with an 8.0.0 server.  No combination of
+	  client/server will work with pre-8.0.0 code.
+
+	- Upgrading from pre-8.0.0 code to 8.0.0 and beyond requires
+	  you to change your conserver.cf and conserver.passwd files
+	  because both of the file formats have changed.
+
+	  The conserver.cf file changes are so major that there is a
+	  convert program available in the conserver subdirectory.  Just
+	  run './conserver/convert <old-cf-file>' and it will attempt a
+	  conversion to the new format, sending it to stdout.  Any errors
+	  will be printed to stderr.  There are a couple of things
+	  you might need to adjust.  First are the user access lists.
+	  If you are restricting users to certain consoles in your old
+	  conserver.passwd file, you'll need to move those restrictions
+	  into the new conserver.cf file.  Restrictions are set with the
+	  'ro' and 'rw' tags in the configuration file.  Second are the
+	  'access' blocks.  What get produced by the convert program
+	  will be functionally equivalent to the old behavior, but you
+	  may be able to tune things to better suit your environment.
+
+	  The conserver.passwd file's console restrictions have moved,
+	  as described above.  So to convert the conserver.passwd file,
+	  all you really need to do is something like:
+
+		awk -F: '{print $1 ":" $2}' <old-passwd-file>
+
+	  If you have comments or continuation lines in your file,
+	  you'll have to do a bit more cleanup to strip out the third
+	  field (which is what the awk command is intending to do).
+
+	- Conserver no longer trusts reverse DNS information by default.
+	  If you use the --with-trustrevdns configure flag, you can
+	  re-enable the use of gethostbyaddr() [I don't recommended it,
+	  however].  If you are using domain names in access lists,
+	  you'll either need to change those to use hostnames and/or ip
+	  addresses/ranges or use the --with-trustrevdns flag.  For
+	  example, if you have (in the
+	  8.0.0 format):
+
+		allowed conserver.com;  # allow *.conserver.com
+
+	  then you'll need to worry about this change.  If you only use
+	  full hostnames, you shouldn't have to do anything.

-	- If SSL support is compiled into the code, older versions of
-	  the client and server are, by default, incompatible because
-	  encrypted connections are a requirement.  Use of the -E flag in
-	  the client and/or server can work around this (but I discourage

PROTOCOL

+			   Conserver Protocol
+			   ==================
+
+
+What Is This?
+-------------
+
+The following is an attempt to describe the client/server protocol used
+between the server (conserver) and the client (console).  This document
+bases it's information on conserver version 8.1.4, as it's the release
+currently available.  If there are changes to the client/server
+protocol, the INSTALL file should reference them and, ideally, this
+document will be updated.
+
+The information is looked at from the point of the server, since it's
+the server that controls all information and triggers actions on the
+client (like a suspend).  The client's perspective should be obvious
+from this information.
+
+
+SSL
+---
+
+The client and server can negotiate an SSL connection.  As far as the
+code is concerned, the SSL "layer" is transparent.  Data is sent and
+received just as if it was unencrypted.  Therefore, aside bringing up
+the SSL connection, the SSL bits are unimportant from a protocol
+standpoint.  The client and server still send and receive the same
+information - it just happens to be encrypted to everyone else.
+
+
+"On-The-Wire" Data
+------------------
+
+The low-level, "on-the-wire" data is encapsulated similar to the telnet
+protocol.  All data is sent "as-is" with the exception of 0xFF.  0xFF is
+used as a "command character" and both the client and server expect to
+see a predefined option after it.  The possible options are: 0xFF, 'E',
+'G', 'Z', and '.'.
+
+The 0xFF option says to use the literal character 0xFF.  So, if there is
+a 0xFF character in the data stream to be sent, the code will send two
+0xFF characters (it's similar to using '\\' in C strings to embed a
+'\').
+
+The other options are used in various contexts, which will be described
+in detail below.
+
+
+Life As A Server
+----------------
+
+There are three different interfaces presented to clients by the server.
+I'm going to name the three modes "master", "group", and "console".  The
+first two are line-based, and the third is character-based.
+
+To understand the differences, I must outline how conserver manages
+consoles.  When conserver starts, it reads the configuration file,
+listens on the master socket, and, for each group of consoles it must
+manage (where the group size is set by -m), it forks off a copy of
+itself.  Those child processes are what actually connect to the consoles
+and they each listen on a new socket for client connections.  So, you
+end up with a parent process (that knows about all consoles) that
+manages the child processes (that know only about consoles it manages),
+and everyone is listening on an individual socket for connections from
+clients.
+
+The parent process interacts with clients in "master" mode.  That mode
+expects line-based commands and responds similarly.  Because it's the
+master, it understands a certain set of commands that are different than
+in "group" mode.
+
+The child processes interact with clients in "group" mode first, and
+negotiate a change to "console" mode when a client requests a connection
+to a specific console.
+
+
+"master" Mode
+-------------
+
+When parent process gets a connection from a client, it either sends an
+"ok" string to signal it's ready or an error message (like "access from
+your host is refused") and the connection is dropped.  At this point,
+there are a small number of commands recognized by the server, since
+most are restricted to "logged in" clients.  Here's the list of
+available commands:
+
+    exit   disconnect
+    help   this help message
+    login  log in
+    ssl    start ssl session
+
+An "exit" is sent a "goodbye" response and the connection is dropped.  A
+"help" is sent the list above.  A "ssl" is sent an "ok" response and
+then the server expects the client to negotiate an ssl connection.  A
+"login" requires one argument (the username) and is either sent an "ok",
+meaning the client is logged in, or a "passwd?" followed by the local
+hostname, asking for the user's password, which it expects next.  If the
+client sends a valid password, an "ok" is sent, otherwise an error
+message and the connection is dropped.
+
+Upon successful login, the commands available are:
+
+    call      provide port for given console
+    exit      disconnect
+    groups    provide ports for group leaders
+    help      this help message
+    master    provide a list of master servers
+    pid       provide pid of master process
+    quit*     terminate conserver (SIGTERM)
+    restart*  restart conserver (SIGHUP)
+    version   provide version info for server
+    * = requires admin privileges
+
+"exit" and "help" are the same as before the client logged login.
+
+The "call" command expects one argument, the console name to connect to.
+The server will respond with either a port number (if it's a locally
+managed console), an "@hostname" where hostname is the name of the
+remote conserver host managing the console (if it's a remotely managed
+console), or an error message (possibly multi-line).  The client is not
+disconnected, whatever the response.
+
+The "groups" command responds with a colon-separated list of port
+numbers, which correspond to each of the child processes running on the
+local host.  The client is not disconnected.
+
+The "master" command responds with a colon-separated list of "@hostname"
+names.  The list includes any hosts (including the possibility of the
+local host) which have locally managed consoles.  The client is not
+disconnected.
+
+The "pid" command responds with the pid of the master process (in this
+case, the one the client is talking to).  The client is not
+disconnected.
+
+The "quit" command will shut down conserver, assuming the user has
+administrative access.  It responds with a message starting with "ok" if
+successful, and an error message otherwise (like "unauthorized
+command").  The client is disconnected if it's successful.
+
+The "restart" command will shut down conserver, assuming the user has
+administrative access.  It responds with a message starting with "ok" if
+successful, and an error message otherwise (like "unauthorized
+command").  The client is not disconnected.
+
+The "version" command responds with the version string.  The client is
+not disconnected.
+
+
+"group" Mode
+------------
+
+When a child process gets a connection from a client, it either sends an
+"ok" string to signal it's ready or an error message (like "access from
+your host is refused") and the connection is dropped.  At this point,
+"group" mode acts just like "master" mode.  Once the client successfully
+logs in, however, "group" mode has the recognizes the following
+commands:
+
+    broadcast    send broadcast message
+    call         connect to given console
+    disconnect*  disconnect the given user(s)
+    examine      examine port and baud rates
+    exit         disconnect
+    group        show users in this group
+    help         this help message
+    hosts        show host status and user
+    info         show console information
+    textmsg      send a text message
+    * = requires admin privileges
+
+The "exit" and "help" commands are like the others documented above.
+
+The "broadcast" command expects a text string of the message to be sent
+to all users connected to this process.  An "ok" is sent as a response.
+
+The "call" command expects one argument, the console name to connect to,
+just like in "master" mode.  The difference here is that this requests
+the server to attach the client to the console and go into "console"
+mode.  If the attachment is successful, the response will begin with a
+'[' character.  If not, an error message is returned.  The success
+responses are:
+
+    [console is read-only]	 - console is read only
+    [read-only -- initializing]	 - console is initializing, and
+				   read-only for the time being
+    [line to console is down]	 - console is down
+    [attached]			 - attached read-write
+    [spy]			 - attached read-only
+
+
+The "disconnect" command expects an argument of the form "user@console"
+where either the "user" or "@console" part may be omitted.  Upon
+success, a response of the form "ok -- disconnected X users" is sent,
+where X is the number of users disconnected.  If a user is unauthorized
+or some other problem occurs, an error message (like "unauthorized
+command") is sent.
+
+The "examine" command returns a list of console information of the form
+that 'console -x' shows.
+
+The "group" command returns a list of console information of the form
+that 'console -w' shows.
+
+The "hosts" command returns a list of console information of the form
+that 'console -u' shows.
+
+The "info" command returns a list of console information of the form
+that 'console -i' shows.
+
+The "textmsg" command expects two arguments, the first being the
+recipient of the message in the form "user@console" (again, where the
+"user" or "@console" portion may be omitted) and the second being the
+string, like the "broadcast" command.  The server returns "ok".
+
+
+"console" Mode
+--------------
+
+As mentioned above, "console" mode is obtained by using the "call"
+command when connected to a child processes operating in "group" mode.
+
+"console" mode should look very familiar to a user of conserver, as it's
+what the user interacts with when connected to a console.  There's
+really nothings special here.  Each character received from the client
+is compared to the escape sequence, and if it matches, an action occurs
+on the server side.  If it doesn't match the escape sequence, the data
+is sent on to the console.  All data received from the console is sent
+to the client(s).  Of course, there are certain exceptions to these
+rules, based on the state of the console and the state of the client.
+And, certain escape sequences cause special behaviors to occur.
+
+Most escape sequences cause the server to send information back to the
+user.  Stuff like "^Ecw", "^Eci", and "^Ecu" are examples.  The escape
+sequence is absorbed by the server, the server sends the client a
+variety of information, and things continue as before.
+
+The more "interesting" escape sequences are the following.
+
+"^Ec;"  The server sends a 0xFF,'G' command sequence to the client, to
+	signal a wish to move to a new console.  The client then gets
+	put into the same state as the "^Ecz" sequence (paused), which
+	gives the client a chance to either resume the connection or
+	disconnect.
+
+"^Ec|"  The server sends a 0xFF,'E' command sequence to the client, to
+	signal a wish to have the client program interact with a
+	program, as opposed to the user.  The server discards all data
+	until it receives one of the following command sequences from
+	the client:
+
+	    0xFF,'E'	Signals successful redirection of interaction to
+			a program.  The server then responds with "[rw]"
+			or "[ro]" to tell the client whether or not they
+			have read-write access.  If not, the client
+			should abort the program and send the abort
+			command sequence below, as other data received by
+			the server will just get dropped.
+
+	    0xFF,'.'	Abort the operation.  The server assumes the
+			redirection didn't happen and returns the client
+			to it's normal mode.
+
+	The server keeps the client in the "redirected" state until it
+	receives a 0xFF,'.' command sequence from the client (which
+	usually occurs when the client command terminates).
+
+	If the client is "bumped" from read-write to read-only by
+	another user, the server will send the client a 0xFF,'.' command
+	sequence to tell it to abort the redirection and return control
+	back to the user.
+
+"^Ecz"  The server sends a 0xFF,'Z' command sequence to the client, to
+	signal a wish to suspend to client process.  The client is then
+	put into a "paused" state where it receives no more data from
+	the server.  When the client is ready to resume receiving data,
+	it sends a character of data to the server, at which point the
+	server discards the character and sends back a status message of
+	the form " -- MSG]".  The current set of possible messages are:
+
+	    " -- line down]"
+	    " -- read-only]"
+	    " -- attached (nologging)]"
+	    " -- attached]"
+	    " -- spy mode]"

+I put together the sample configuration files in this directory in hopes

+configuration file format.  Each of the files are syntatically correct,
+but have never actually been used.
+
+Each file is basically built upon the previous...theoretically, if not
+actually.  Hopefully they'll help show some of the cool things you can
+do with the configuration file and help those trying to figure out how
+they should even start.
+
+    simple.cf - A very simple, one console config file
+
+    basic.cf - A config with a couple consoles, mostly using defaults
+

+
+    average-distributed.cf - Taking average.cf to multiple conserver
+			     hosts with overrides on those hosts

+.SH PROTOCOL
+.PP
+The protocol used to interact with the
+.B conserver
+daemon has two basic styles.
+The first style is the initial line-based mode, which occurs before
+connecting to a console.
+The second style is the character-based, escape-sequence mode, while
+connected to a console.
+.PP
+The initial line-based mode begins the same for both the master process
+and it's children.
+Upon a successful (non-rejected) client connection, an ``ok'' is sent.
+The client then issues a command and the server responds to it with a
+result string (``ok'' being the sign of success for most commands).
+The commands available are ``help'', ``ssl'' (if
+SSL was built into the code), ``login'', and ``exit''.
+Using the ``login'' command, the client authenticates and gains access to
+the extended command set.
+This is where the master process and it's children differ.
+The master process gives the client access to global commands, and the
+child provides commands for interacting with the consoles it manages.
+The ``help'' command, in both cases, will provide a complete
+list of commands and a short description of what they do.
+.PP
+The second, character-based, style of interaction occurs when the client
+issues the ``call'' command with a child process.
+This command connects the client to a console and, at that point, relays
+all traffic between the client and the console.
+There is no more command-based interaction between the client and the server,
+any interaction with the server is done with the default escape sequence.
+.PP
+This is, by no means, a complete description of the entire client/server
+interaction.
+It is, however, a brief explanation in order to give a idea of
+what the program does.  See the
+.B \s-1PROTOCOLS\s0
+file in the distribution for further details.

+.TH CHAT 8 "22 May 1999" "Chat Version 1.22"
+.SH "NAME"
+chat \- Automated conversational script with a modem
+.SH "SYNOPSIS"
+.B chat
+[
+.I options
+]
+.I script
+.SH "DESCRIPTION"
+.LP
+The \fIchat\fR program defines a conversational exchange between the
+computer and the modem. Its primary purpose is to establish the
+connection between the Point-to-Point Protocol Daemon (\fIpppd\fR) and
+the remote's \fIpppd\fR process.
+.SH "OPTIONS"
+.TP
+.B -f \fI<chat file>
+Read the chat script from the chat \fIfile\fR. The use of this option
+is mutually exclusive with the chat script parameters. The user must
+have read access to the file. Multiple lines are permitted in the
+file. Space or horizontal tab characters should be used to separate
+the strings.
+.TP
+.B -t \fI<timeout>
+Set the timeout for the expected string to be received. If the string
+is not received within the time limit then the reply string is not
+sent. An alternate reply may be sent or the script will fail if there
+is no alternate reply string. A failed script will cause the
+\fIchat\fR program to terminate with a non-zero error code.
+.TP
+.B -r \fI<report file>
+Set the file for output of the report strings. If you use the keyword
+\fIREPORT\fR, the resulting strings are written to this file. If this
+option is not used and you still use \fIREPORT\fR keywords, the
+\fIstderr\fR file is used for the report strings.
+.TP
+.B -e
+Start with the echo option turned on. Echoing may also be turned on
+or off at specific points in the chat script by using the \fIECHO\fR
+keyword. When echoing is enabled, all output from the modem is echoed
+to \fIstderr\fR.
+.TP
+.B -E
+Enables environment variable substituion within chat scripts using the
+standard \fI$xxx\fR syntax.
+.TP
+.B -v
+Request that the \fIchat\fR script be executed in a verbose mode. The
+\fIchat\fR program will then log the execution state of the chat
+script as well as all text received from the modem and the output
+strings sent to the modem.  The default is to log through the SYSLOG;
+the logging method may be altered with the -S and -s flags. SYSLOGs
+are logged to facility LOG_LOCAL2.
+.TP
+.B -V
+Request that the \fIchat\fR script be executed in a stderr verbose
+mode. The \fIchat\fR program will then log all text received from the
+modem and the output strings sent to the modem to the stderr device. This
+device is usually the local console at the station running the chat or
+pppd program.
+.TP
+.B -s
+Use stderr.  All log messages from '-v' and all error messages will be
+sent to stderr.
+.TP
+.B -S
+Do not use the SYSLOG.  By default, error messages are sent to the
+SYSLOG.  The use of -S will prevent both log messages from '-v' and
+error messages from being sent to the SYSLOG (to facility LOG_LOCAL2).
+.TP
+.B -T \fI<phone number>
+Pass in an arbitary string, usually a phone number, that will be
+substituted for the \eT substitution metacharacter in a send string.
+.TP
+.B -U \fI<phone number 2>
+Pass in a second string, usually a phone number, that will be
+substituted for the \eU substitution metacharacter in a send string.
+This is useful when dialing an ISDN terminal adapter that requires two
+numbers.
+.TP
+.B script
+If the script is not specified in a file with the \fI-f\fR option then
+the script is included as parameters to the \fIchat\fR program.
+.SH "CHAT SCRIPT"
+.LP
+The \fIchat\fR script defines the communications.
+.LP
+A script consists of one or more "expect-send" pairs of strings,
+separated by spaces, with an optional "subexpect-subsend" string pair,
+separated by a dash as in the following example:
+.IP
+ogin:-BREAK-ogin: ppp ssword: hello2u2
+.LP
+This line indicates that the \fIchat\fR program should expect the string
+"ogin:". If it fails to receive a login prompt within the time interval
+allotted, it is to send a break sequence to the remote and then expect the
+string "ogin:". If the first "ogin:" is received then the break sequence is
+not generated.
+.LP
+Once it received the login prompt the \fIchat\fR program will send the
+string ppp and then expect the prompt "ssword:". When it receives the
+prompt for the password, it will send the password hello2u2.
+.LP
+A carriage return is normally sent following the reply string. It is not
+expected in the "expect" string unless it is specifically requested by using
+the \er character sequence.
+.LP
+The expect sequence should contain only what is needed to identify the
+string. Since it is normally stored on a disk file, it should not contain
+variable information. It is generally not acceptable to look for time
+strings, network identification strings, or other variable pieces of data as
+an expect string.
+.LP
+To help correct for characters which may be corrupted during the initial
+sequence, look for the string "ogin:" rather than "login:". It is possible
+that the leading "l" character may be received in error and you may never
+find the string even though it was sent by the system. For this reason,
+scripts look for "ogin:" rather than "login:" and "ssword:" rather than
+"password:".
+.LP
+A very simple script might look like this:
+.IP
+ogin: ppp ssword: hello2u2
+.LP
+In other words, expect ....ogin:, send ppp, expect ...ssword:, send hello2u2.
+.LP
+In actual practice, simple scripts are rare. At the vary least, you
+should include sub-expect sequences should the original string not be
+received. For example, consider the following script:
+.IP
+ogin:--ogin: ppp ssword: hello2u2
+.LP
+This would be a better script than the simple one used earlier. This would look
+for the same login: prompt, however, if one was not received, a single
+return sequence is sent and then it will look for login: again. Should line
+noise obscure the first login prompt then sending the empty line will
+usually generate a login prompt again.
+.SH "COMMENTS"
+Comments can be embedded in the chat script. A comment is a line which
+starts with the \fB#\fR (hash) character in column 1. Such comment
+lines are just ignored by the chat program. If a '#' character is to
+be expected as the first character of the expect sequence, you should
+quote the expect string, or give its octal value, `\e043'.
+In a script file if you want to wait for a prompt that starts with a '#'
+character, you would have to write something like this:
+.IP
+# Now wait for the prompt and send logout string
+.br
+\'# ' logout
+.SH "SENDING DATA FROM A FILE"
+If the string to send starts with an at sign (@), the rest of the
+string is taken to be the name of a file to read to get the string to
+send.  If the last character of the data read is a newline, it is
+removed.  The file can be a named pipe (or fifo) instead of a regular
+file.  This provides a way for \fBchat\fR to communicate with another
+program, for example, a program to prompt the user and receive a
+password typed in.
+.SH "ABORT STRINGS"
+Many modems will report the status of the call as a string. These
+strings may be \fBCONNECTED\fR or \fBNO CARRIER\fR or \fBBUSY\fR. It
+is often desirable to terminate the script should the modem fail to
+connect to the remote. The difficulty is that a script would not know
+exactly which modem string it may receive. On one attempt, it may
+receive \fBBUSY\fR while the next time it may receive \fBNO CARRIER\fR.
+.LP
+These "abort" strings may be specified in the script using the \fIABORT\fR
+sequence. It is written in the script as in the following example:
+.IP
+ABORT BUSY ABORT 'NO CARRIER' '' ATZ OK ATDT5551212 CONNECT
+.LP
+This sequence will expect nothing; and then send the string ATZ. The
+expected response to this is the string \fIOK\fR. When it receives \fIOK\fR,
+the string ATDT5551212 to dial the telephone. The expected string is
+\fICONNECT\fR. If the string \fICONNECT\fR is received the remainder of the
+script is executed. However, should the modem find a busy telephone, it will
+send the string \fIBUSY\fR. This will cause the string to match the abort
+character sequence. The script will then fail because it found a match to
+the abort string. If it received the string \fINO CARRIER\fR, it will abort
+for the same reason. Either string may be received. Either string will
+terminate the \fIchat\fR script.
+.SH "CLR_ABORT STRINGS"
+This sequence allows for clearing previously set \fBABORT\fR strings.
+\fBABORT\fR strings are kept in an array of a pre-determined size (at
+compilation time); \fBCLR_ABORT\fR will reclaim the space for cleared
+entries so that new strings can use that space.
+.SH "SAY STRINGS"
+The \fBSAY\fR directive allows the script to send strings to the user
+at the terminal via standard error.  If \fBchat\fR is being run by
+pppd, and pppd is running as a daemon (detached from its controlling
+terminal), standard error will normally be redirected to the file
+/etc/ppp/connect-errors.
+.LP
+\fBSAY\fR strings must be enclosed in single or double quotes. If
+carriage return and line feed are needed in the string to be output,
+you must explicitly add them to your string.
+.LP
+The SAY strings could be used to give progress messages in sections of
+the script where you want to have 'ECHO OFF' but still let the user
+know what is happening.  An example is:
+.IP
+ABORT BUSY
+.br
+ECHO OFF
+.br
+SAY "Dialling your ISP...\en"
+.br
+\'' ATDT5551212
+.br
+TIMEOUT 120
+.br
+SAY "Waiting up to 2 minutes for connection ... "
+.br
+CONNECT ''
+.br
+SAY "Connected, now logging in ...\n"
+.br
+ogin: account
+.br
+ssword: pass
+.br
+$ \c
+SAY "Logged in OK ...\n"
+\fIetc ...\fR
+.LP
+This sequence will only present the SAY strings to the user and all
+the details of the script will remain hidden. For example, if the
+above script works, the user will see:
+.IP
+Dialling your ISP...
+.br
+Waiting up to 2 minutes for connection ... Connected, now logging in ...
+.br
+Logged in OK ...
+.LP
+.SH "REPORT STRINGS"
+A \fBreport\fR string is similar to the ABORT string. The difference
+is that the strings, and all characters to the next control character
+such as a carriage return, are written to the report file.
+.LP
+The report strings may be used to isolate the transmission rate of the
+modem's connect string and return the value to the chat user. The
+analysis of the report string logic occurs in conjunction with the
+other string processing such as looking for the expect string. The use
+of the same string for a report and abort sequence is probably not
+very useful, however, it is possible.
+.LP
+The report strings to no change the completion code of the program.
+.LP
+These "report" strings may be specified in the script using the \fIREPORT\fR
+sequence. It is written in the script as in the following example:
+.IP
+REPORT CONNECT ABORT BUSY '' ATDT5551212 CONNECT '' ogin: account
+.LP
+This sequence will expect nothing; and then send the string
+ATDT5551212 to dial the telephone. The expected string is
+\fICONNECT\fR. If the string \fICONNECT\fR is received the remainder
+of the script is executed. In addition the program will write to the
+expect-file the string "CONNECT" plus any characters which follow it
+such as the connection rate.
+.SH "CLR_REPORT STRINGS"
+This sequence allows for clearing previously set \fBREPORT\fR strings.
+\fBREPORT\fR strings are kept in an array of a pre-determined size (at
+compilation time); \fBCLR_REPORT\fR will reclaim the space for cleared
+entries so that new strings can use that space.
+.SH "ECHO"
+The echo options controls whether the output from the modem is echoed
+to \fIstderr\fR. This option may be set with the \fI-e\fR option, but
+it can also be controlled by the \fIECHO\fR keyword. The "expect-send"
+pair \fIECHO\fR \fION\fR enables echoing, and \fIECHO\fR \fIOFF\fR
+disables it. With this keyword you can select which parts of the
+conversation should be visible. For instance, with the following
+script:
+.IP
+ABORT   'BUSY'
+.br
+ABORT   'NO CARRIER'
+.br
+''      ATZ
+.br
+OK\er\en  ATD1234567
+.br
+\er\en    \ec
+.br
+ECHO    ON
+.br
+CONNECT \ec
+.br
+ogin:   account
+.LP
+all output resulting from modem configuration and dialing is not visible,
+but starting with the \fICONNECT\fR (or \fIBUSY\fR) message, everything
+will be echoed.
+.SH "HANGUP"
+The HANGUP options control whether a modem hangup should be considered
+as an error or not.  This option is useful in scripts for dialling
+systems which will hang up and call your system back.  The HANGUP
+options can be \fBON\fR or \fBOFF\fR.
+.br
+When HANGUP is set OFF and the modem hangs up (e.g., after the first
+stage of logging in to a callback system), \fBchat\fR will continue
+running the script (e.g., waiting for the incoming call and second
+stage login prompt). As soon as the incoming call is connected, you
+should use the \fBHANGUP ON\fR directive to reinstall normal hang up
+signal behavior.  Here is an (simple) example script:
+.IP
+ABORT   'BUSY'
+.br
+''      ATZ
+.br
+OK\er\en  ATD1234567
+.br
+\er\en    \ec
+.br
+CONNECT \ec
+.br
+\'Callback login:' call_back_ID
+.br
+HANGUP OFF
+.br
+ABORT "Bad Login"
+.br
+\'Callback Password:' Call_back_password
+.br
+TIMEOUT 120
+.br
+CONNECT \ec
+.br
+HANGUP ON
+.br
+ABORT "NO CARRIER"
+.br
+ogin:--BREAK--ogin: real_account
+.br
+\fIetc ...\fR
+.LP
+.SH "TIMEOUT"
+The initial timeout value is 45 seconds. This may be changed using the \fB-t\fR
+parameter.
+.LP
+To change the timeout value for the next expect string, the following
+example may be used:
+.IP
+ATZ OK ATDT5551212 CONNECT TIMEOUT 10 ogin:--ogin: TIMEOUT 5 assword: hello2u2
+.LP
+This will change the timeout to 10 seconds when it expects the login:
+prompt. The timeout is then changed to 5 seconds when it looks for the
+password prompt.
+.LP
+The timeout, once changed, remains in effect until it is changed again.
+.SH "SENDING EOT"
+The special reply string of \fIEOT\fR indicates that the chat program
+should send an EOT character to the remote. This is normally the
+End-of-file character sequence. A return character is not sent
+following the EOT.
+.PR
+The EOT sequence may be embedded into the send string using the
+sequence \fI^D\fR.
+.SH "GENERATING BREAK"
+The special reply string of \fIBREAK\fR will cause a break condition
+to be sent. The break is a special signal on the transmitter. The
+normal processing on the receiver is to change the transmission rate.
+It may be used to cycle through the available transmission rates on
+the remote until you are able to receive a valid login prompt.
+.PR
+The break sequence may be embedded into the send string using the
+\fI\eK\fR sequence.
+.SH "ESCAPE SEQUENCES"
+The expect and reply strings may contain escape sequences. All of the
+sequences are legal in the reply string. Many are legal in the expect.
+Those which are not valid in the expect sequence are so indicated.
+.TP
+.B ''
+Expects or sends a null string. If you send a null string then it will still
+send the return character. This sequence may either be a pair of apostrophe
+or quote characters.
+.TP
+.B \eb
+represents a backspace character.
+.TP
+.B \ec
+Suppresses the newline at the end of the reply string. This is the only
+method to send a string without a trailing return character. It must
+be at the end of the send string. For example,
+the sequence hello\ec will simply send the characters h, e, l, l, o.
+.I (not valid in expect.)
+.TP
+.B \ed
+Delay for one second. The program uses sleep(1) which will delay to a
+maximum of one second.
+.I (not valid in expect.)
+.TP
+.B \eK
+Insert a BREAK
+.I (not valid in expect.)
+.TP
+.B \en
+Send a newline or linefeed character.
+.TP
+.B \eN
+Send a null character. The same sequence may be represented by \e0.
+.I (not valid in expect.)
+.TP
+.B \ep
+Pause for a fraction of a second. The delay is 1/10th of a second.
+.I (not valid in expect.)
+.TP
+.B \eq
+Suppress writing the string to the SYSLOG. The string ?????? is
+written to the log in its place.
+.I (not valid in expect.)
+.TP
+.B \er
+Send or expect a carriage return.
+.TP
+.B \es
+Represents a space character in the string. This may be used when it
+is not desirable to quote the strings which contains spaces. The
+sequence 'HI\ TIM' and HI\esTIM are the same.
+.TP
+.B \et
+Send or expect a tab character.
+.TP
+.B \eT
+Send the phone number string as specified with the \fI-T\fR option
+.I (not valid in expect.)
+.TP
+.B \eU
+Send the phone number 2 string as specified with the \fI-U\fR option
+.I (not valid in expect.)
+.TP
+.B \e\e
+Send or expect a backslash character.
+.TP
+.B \eddd
+Collapse the octal digits (ddd) into a single ASCII character and send that
+character.
+.I (some characters are not valid in expect.)
+.TP
+.B \^^C
+Substitute the sequence with the control character represented by C.
+For example, the character DC1 (17) is shown as \^^Q.
+.I (some characters are not valid in expect.)
+.SH "ENVIRONMENT VARIABLES"
+Environment variables are available within chat scripts, if  the \fI-E\fR
+option was specified in the command line. The metacharacter \fI$\fR is used
+to introduce the name of the environment variable to substitute. If the
+substition fails, because the requested environment variable is not set,
+\fInothing\fR is replaced for the variable.
+.SH "TERMINATION CODES"
+The \fIchat\fR program will terminate with the following completion
+codes.
+.TP
+.B 0
+The normal termination of the program. This indicates that the script
+was executed without error to the normal conclusion.
+.TP
+.B 1
+One or more of the parameters are invalid or an expect string was too
+large for the internal buffers. This indicates that the program as not
+properly executed.
+.TP
+.B 2
+An error occurred during the execution of the program. This may be due
+to a read or write operation failing for some reason or chat receiving
+a signal such as SIGINT.
+.TP
+.B 3
+A timeout event occurred when there was an \fIexpect\fR string without
+having a "-subsend" string. This may mean that you did not program the
+script correctly for the condition or that some unexpected event has
+occurred and the expected string could not be found.
+.TP
+.B 4
+The first string marked as an \fIABORT\fR condition occurred.
+.TP
+.B 5
+The second string marked as an \fIABORT\fR condition occurred.
+.TP
+.B 6
+The third string marked as an \fIABORT\fR condition occurred.
+.TP
+.B 7
+The fourth string marked as an \fIABORT\fR condition occurred.
+.TP
+.B ...
+The other termination codes are also strings marked as an \fIABORT\fR
+condition.
+.LP
+Using the termination code, it is possible to determine which event
+terminated the script. It is possible to decide if the string "BUSY"
+was received from the modem as opposed to "NO DIAL TONE". While the
+first event may be retried, the second will probably have little
+chance of succeeding during a retry.
+.SH "SEE ALSO"
+Additional information about \fIchat\fR scripts may be found with UUCP
+documentation. The \fIchat\fR script was taken from the ideas proposed
+by the scripts used by the \fIuucico\fR program.
+.LP
+uucp(1), uucico(8)
+.SH "COPYRIGHT"
+The \fIchat\fR program is in public domain. This is not the GNU public
+license. If it breaks then you get to keep both pieces.
