Brian Sheehan <sheehan_at_scripps.edu>
Paul Gavazzi <gavazzi_at_access.digex.net>
Christian Miranda <cmiranda_at_gmd.com.pe>
The response from Christian Miranda triggered a few synapses.

UNIX-9600|9600 Baud dial-out to another UNIX system:\
:el=^U^C^R^O^D^S^Q_at_:ie=#%$:oe=^D:tc=dial9600:\
:dv=/dev/ttyd0:
