The RS-232-C direct connect enables local communications up to a distance of
50 feet. The RS-422-A balanced direct connect enables local communication up
to 4000 feet at data rates up to 19,200 bits per second.
The universal modem bypass (DCF6927) is a self-contained, stand-alone device
enabling local communications over a distance of up to 2500 feet over ordinary
telephone cable. It is designed as an inexpensive replacement for a modem
over this limited distance.
