Are you using the standard ISA serial ports for your test? There are several multiport cards out there that have onboard processors. Also there are some "enhanced" 16550 based cards that someone has written a patch to the sio driver to enable up 460kbps. A terminal server will need more than 2 ports that are standard on PC motherboards. I've been running several boxes with the Cyclades cards for over a year and am just bring up a new terminal server using the Cyclades 16z card which is "supposed" to support up to 920kbps. diana Diana Eichert IT Manager McKinley Paper Company deeiche@mckinleypaper.com Tele: 505/290-0153 PGP public key finger: deichert@ts.shopnet.com
