Using a cable that connects the Data Terminal Ready (DTR) signal will ensure automatic log off when the terminal
is unplugged. When connecting the RS-232 port to a modem, a null modem cable should be used. Ensure that the
modem's Carrier Detect (CD) and DTR functions are enabled. This will allow the modem connection to terminate
properly when the PMU or PAU drops Data Set Ready (DSR) and the unit will log off when the modem drops
CD. The following connections are required to make the modem work correctly (see
