I checked my /etc/ttys and I had an error ctsrts instead of rtscts that man
ttys says to use. I did have crtscts in /etc/ppp/options, but maybe you
need both to be correct.

I made the cable myself from the documentation in the Sun user books. I
think it is correct, but I'm not sure how to be sure except to use it.

Thanks for the help. I'll reboot tonight and see if it is any better.

BTW what speed do you set in ppp/options? I've been using 38400.
