[Fixed that] This did not help with /dev/cua being busy. It turns out that if I had the getty sitting on /dev/ttyda, I couldn't get hold of /dev/cua. It seems to me that ttyda (dial in) cua (dial out) were originally designed to somehow share the serial port (A in this case), however ttyda seems to hold on to the port so that cua couldn't grab a hold of it. Some say this is a 2.0 bug and I should get 2.1 (btw, where can I get 2.1?). So effectively what I had to do was to turn off the getty on ttyda. We had some similar problems. The problem we were having was again related to modem setup. Our modem was holding DTR incorrectly, and it kept causing the machine to think the modem was ready for a login. It worked after some more modem configuration work . . . Now, although I can dial out, for some reason I can't escape back to my local kermit. I'm using 4E, so perhaps there's a problem there. I'm working on getting kermit 5A... Is this because of the getty not being there? I have to kill -9 kermit now. I suppose it's better than not being able to dial out at all (or at least better than from single user mode). This is actually a problem with the machine, not kermit or the modem. The problem is that the ctrl-shift-\, where \ is off the keypad, doesn't exist on the new keyboards. There are a couple fixes. Stuart2.11 has code to spoof this, so that your programs (command line programs, that is). Otherwise, use kermit's 'set escape-character' command to set the character to 29 (ctrl-], I think). That can be added to your .kermrc file. Btw, I just saw a post about the same problem. The person said that tip and kermit don't work on /dev/cua, but rather on /dev/cub. I don't believe it's a "port A vs port B" problem. It's not.
