Hit Ctrl+Break? you want to send a BREAK over the serial line. from cu, you do this by typing ~# at the start of a line (i.e. press enter first). If you're connecting over SSH, you need to escape the first tilde since it's also used by SSH: ~~# > 9. and I'm set with the OK> prompt? > > When exactly do I hit Ctrl+Break?

Correct my procedure if it's wrong. doesn't matter. if you don't see the startup messages, verify the cable really is wired correctly, and/or plug in your rs232 tester (what do you mean you don't have one ;-) and check the lines. >>> But the cable is short, so I got a regular extension cable to >>> hook up to it. >> >> It might be advisable to get a longer null modem cable, as you know.. >> the different between a null modem and strait through cable is the >> pinout. there's no problem to plug a normal modem cable into a null modem cable to make it longer..
