Re: 735/125 serial console problems



Thanks for all the possibilities. I am running a 233MHz AMD K6 PC,
Debian.  I'm not sure what the problem was, but I tried it once again
last night and it was working perfectly. Go figure.  Perhaps I had a
screen session open in the background that was interfering, or maybe I
had a heavy load on my system and it was the interrupt thing. It worked
in both minicom and screen, BTW.

    screen /dev/ttyS1 9600,ixoff

and minicom with the 9600 8N1 settings, no hardware or software control.

Thanks!
Hans :)
