Hi Garrett,

in my opinion, and I think most of the people here would agree, 
get a terminal server. The serial lines themselves aren't going to 
be any more or less pain, but the rest is fairly simple (involves
tnetDev, drvSerial, drvAscii for all of them, and a few lines in
your startup file).

Aloha,

Maren
