It seems that Annex was the most popular terminal server. Some of the
others brands were Lantronix, Cisco, Digi International, and Central Data.
All of them seemed to have the capability to password protect access to the
terminal server, and all of them seemed to have a way of forcing a port free.
Noone reported any problems of the terminal server sending a break signal to
the server.
Here's some other miscellaneous notes:
- One person attached the ethernet port on terminal server to a specific
system via a cross-over cable. This way people would have to login to
that specific system prior to connecting to the terminal server (for added
security).
- To protect against the break signal, the eeprom "ttya-ignore-cd" can be
set to "true" and the "ttya-rts-dtr-off" can be set to "false".
- Numerous people mentioned opening a bunch of xterms so that they can capture
the console output.
- Others used a UNIX box with a multiport serial card instead of a terminal
server.
- Some preferred using a KVM (Keyboard, Video, Mouse) switch instead of a
terminal server configuration.
- Big plus with the terminal server set up is the saving of physical space.
