ConMan is a serial console management program designed to support a large
number of console devices and simultaneous users. It supports:
- local serial devices
- remote terminal servers (via the telnet protocol)
- IPMI Serial-Over-LAN (via FreeIPMI)
- Unix domain sockets
- external processes (eg, using Expect for telnet/ssh/ipmi-sol connections)

Its features include:
- logging (and optionally timestamping) console device output to file
- connecting to consoles in monitor (R/O) or interactive (R/W) mode
- allowing clients to share or steal console write privileges
- broadcasting client output to multiple consoles
