Forget cu - it does far more than you need. I had to do this once and the
solution I came up with was to write a C program that called out on a hayes
modem line and when it got a 'CONNECT' message it forked a getty. For this to
work the process must attach stdin, stdout and stderr to the outgoing terminal
line and then set itself to be the head of a process group. If not then /dev/tty
will not point to the right device. I do not have the src available on my
current machine however (and I never quite finished it anyway...)
