It's towards the back. Essentially you need a null modem cable to physically connect the computers, then set up /etc/inittab properly (documented in the manual), at which point you should be all set up for file transfer (use Kermit, it's free for both machines and has worked well for us... MS-Kermit also is a terminal emulation package). 9600 baud works fine, I don't think 19200 does, but I could be wrong about that. HOWEVER... trying to back up a file system over this is going to be an overnight affair at 9600 baud, even if you're only filling one Bernoulli cartridge. 40 MB will take approximately 8 hours at 9600 baud, ignoring protocol overhead. :( < Bob | S090726@UMRVMA.UMR.EDU | Funchess > University of Missouri - Rolla Be reasonable: if the university shared my opinions, would I have an ID like S090726 ???
