Title: RE: terminal servers
We've
been using Emulex 2516 terminal servers for many years without
problems
on
Mauna Kea. We've recently installed a couple of Lantronix ETS32PR
terminal
servers which work just as well.
Our
SysAdmin has a slight preference for Lantronix because he was able to
connect
our
Sun consoles to it and Lantronix customer support was
responsive.
Also
the Lantronix can be rack mounted.

I just looked at a Moxa 4 port RS422 server that was floating
around here. I hooked it up to a Linux machine and it mapped the ports
to the Linux tty ports as advertised. I had borrowed this from someone
trying this on a Windows PC and it seemed to work the same way mapping to COM
ports in windows.
In the short test I did things looked good. I had no 422
devices to try though. I have decided to try another deice from Digi
(www.digi.com). My first application is for a terminal server for
IOCs. the Digi model has an RJ45 port that is similar to the ports on a
MVME172 and 2304 that we are using here.
As for playing in a hostile environment, I did this in my
office. Some may consider it hostile but I don't think this fits your
definition.
