The original ser2net config used raw TCP accepters, but conman's
dev="host:port" speaks telnet protocol. This protocol mismatch caused
conman's telnet NVT state machine to strip bare CR characters from
device output — particularly from Dell switches that send \n\r (LF+CR)
line endings — producing stair-stepped and garbled terminal display.
Fix: change ser2net accepter from `tcp,IP,PORT` to
`telnet(rfc2217),tcp,IP,PORT`. With both sides speaking telnet, binary
mode is negotiated and CR/LF translation is handled correctly by the
telnet NVT layer. RFC2217 also enables baud rate negotiation for
future use.
Validated at the byte level: PTY capture confirms all prompts render
cleanly at column 0 with proper CRLF handling across 5+ Enter presses.
All 7 consoles connected, 7 log files actively capturing.

Architecture
- Proxmox hosts: 7 standalone PVE installs managed via PDM
- DNS: Technitium (authoritative) + Pi-hole (recursive) on pfv-netinfra-01/02
- NTP: pfv-netinfra-01/02 (redundant, LAN IPs, stratum 2/3)
- Production: Cloudron VPS in Reston VA (this cluster is R&D only)
- Backups: Proxmox Backup Server (PBS)
