Of course, in this arrangement, it makes sense. One Max, one modem in.
What I'm getting at is that where there may be more than one Max (or
anything else) in the same place, it might make sense to put in a terminal
server that can handle all the serial ports that are around.
Anyhow, I suppose this is all off topic. Suffice to say that we've
successfully used the serial ports of Maxes to perform remote reboots
without having to use a modem.

One of your links would be a phone line, which could be hooked up to the
terminal server as well.
