Modem port
Terminals which are equipped with a MODEM port, will not
have an RS-485 port. The MODEM port, when installed,
physically replaces the RS-485 port and occupies the same
location - the lower left corner of the badge terminal. It is a 6
position 4-pin female port which will accept a male RJ-11
modular connector.
The internal modem (modulator/demodulator) converts electronic
data into tones which are then transmitted over phone lines. The
modem is compatible with Bell 103/212A and CCITT V.21/V.22
devices. It supports both asynchronous and synchronous (SDLC)
communication and can communicate with a host computer over
phone lines at 300, 1200, and 2400 baud.
