This won't quite work, if the modem really does fail to work at all without
hardware flow control.  It won't work because AFAIK there is no way to set
hardware flow control from within 'cu'.

After you start the 'cu', suspend it (^Z or <ret>~^Z depending how far it's
gone since you ran it) and type "stty -f /dev/tty03 crtscts".  Then you will
be testing the documented behaviour.

To get crtscts turned on all the time on that tty, add "rtscts" (NOT
"crtscts") to the /dev/tty03 line in /etc/ttys and run ttyflags -a or
reboot (which will run ttyflags -a for you).  You could do that, then try
the cu test, too.
