4.7.2 Connecting a Peripheral to a Modem Port
The basic DECsystem 5100 has one modem port, situated between MMJ port

The following procedure describes how to connect a peripheral to one of the
modem ports on the back of the system unit:
Turn off the DECsystem 5100 and the peripheral, by setting the on/off
switches to the off

modem port.
4 If the connector has screws on either side, tighten them with a small
screwdriver.

Turn on the peripheral by setting its on/off switch to the on ( I ) position.
6 Turn on the DECsystem 5100 by setting its on/off switch to the on (I )
position.
