Controlling an External Analog Modem
There are three options for enabling and disabling an external mo-
dem: the Express Configuration Wizard, the WIN 95/NT 4.0 Tool
Tray Icon, or a terminal emulation package. See the section Ex-
press Configuration Tray Tool Menu on page 22 for more informa-
tion on enabling and disabling a modem.
Once the external analog modem is enabled, all further COM ac-
tivity 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 mo-
dem 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.
