The ser2net layer between conman and the serial devices was causing
stair-stepping in terminal output. conman's dev="host:port" uses telnet
protocol, but ser2net's accepter was raw TCP (no telnet mode). The telnet
NVT state machine in conman was stripping bare CR characters from device
output — particularly from Dell switches that use old-style \n\r (LF+CR)
line endings instead of standard \r\n. In telnet, a bare \r not followed
by \n or NUL is non-compliant and gets dropped, leaving bare \n that
causes stair-stepping in the raw-mode terminal.
Fix: conman now opens serial devices directly via the stable udev
symlinks (/dev/consoles/<name>) with seropts, eliminating the telnet
layer entirely. ser2net is stopped and disabled but remains installed
for emergency TCP access (documented workflow: stop conmand, start
ser2net, use telnet, then reverse).
Architecture change:
Before: device → serial → ser2net (raw TCP) → conman (telnet NVT) → terminal
After: device → serial → conman (direct) → terminal
Verified: 7/7 serial devices held by conmand, 7/7 log files capturing,
all \r bytes preserved in terminal output (confirmed via PTY capture).

Agent Gardening Protocol
When making changes to this repo, agents MUST:
- Update
../STATUS.mdif the work changes infrastructure state, completes/starts a task, or discovers a new issue. - Update this file (
docmap.md) if a doc is added, removed, or has a substantive content change. Update the "Last Reviewed" date. - Verify cross-references — any new
.mdfile must be linked from at least one existing doc or this map. - Check for stale paths — after any directory rename or file move,
grep -rn 'old/path' --include='*.md'and fix all references. - Keep code and docs in sync — if you change a script's interface, behavior, or location, update every doc that references it in the same commit.
