Setting Up the Communication Port to Support an External Device

NOTE:
To detect when the external device connection has been lost, the
communication port's DTR lead should be connected to the external device's
DSR lead using a standard EIA-232 crossover cable (the communication
port's DTR lead is monitored for loss of connection). The external device
must be configured to drop DSR when a disconnect occurs, and to ignore
DTR.
Use the External Device Options screen (see
to support an external device such as a modem or a PAD. These options control
call processing for an external device.
