unix and linux net driver

From [e-mail] mentions:

I was working with software flow control (at 38400 baud) so the output
to /dev/cufa resulted in a deadlock.  If the modem does not dial but
shows TR, check hardware flow control by using the device /dev/cufa
with tip. If this results in a deadlock relace your modem cable, for
now replace /dev/cufa with /dev/cua and change the baudrate to 19200.
