I don't *really* know what they mean.. but if you do a file save in 3c5x9cfg to create a 'config file', then edit the config file it has an option that says something about minimum interrupt release time, or something like that. (ok, so I can't remember... ) Anyway I would think that picking server and a high baud rate would 'optimize' the settings for allowing other interrupts/devices access to the cpu/bus whatever... If you select client/no modem and save it, then server/38400 baud and compare the files you'll get an idea what I'm babbling about. It's late.. I'll give up on this for now. :-) -Andrew -- #!/bin/sh - ============================================== echo "Andrew Gillham gillham@andrews.edu" echo "Winix Hacker" #=========================================================
