Assume local control with no control from the modem.

Read my "locks.blurb". Using "stty" to configure a port is ephemerial
in that most applications reconfigure the port. Thus any
modifications made with "stty" are wiped out.
Read my 'serial_suite.tgz'. This is a collection of blurbs about the
care and feeding of the serial ports and some simple programs. There is
a file demonstrating how the lock files should be programmed. There
is a simple getty, a dialer for ppp connections and some other misc
programs.

"termio.blurb" and "locks.blurb" are part of "serial_suite".
