Chapter 3. Installing an Analog Modem
Controlling an External Analog Modem
There are three options for enabling and disabling an external
modem: the Express Configuration Wizard, the WIN 95/NT 4.0
Tool Tray Icon, or a terminal emulation package. See the section
Express Configuration Wizard Tray Tool for more information on
enabling and disabling a modem.
Once the external analog modem is enabled, all further COM
activity is transmitted to the external analog modem connected
to the Express XRT modem port. The external analog modem
RTS and CTS lines are switched over to the PC COM port
directly when the Express XRT is commanded to enable the
external modem port. This allows the external analog modem to
provide flow control as normal.
When the external analog modem is disabled, all further COM
port activity is processed by the ISDN terminal adapter within
the Express XRT.
