50 Express XR/XRT Quick Start Guide 61200.153L1-13
External Analog Modem Not Detected
If the Express Configuration Wizard cannot detect the external
analog mode verify the following:
1. The external analog modem is powered on.
2. The external analog modem is properly installed and
configured for use with the Express Configuration Wizard.
See Configuring an External Modem for more details on the
required settings.
Difficulty with 230.4 kbps Operation
If the Express XR/XRT does not work when the DTE rate is set
to 230.4 kbps inside Windows, verify the following:
1. Verify that switch 1 on the back of the Express XR/XRT is
set to off (up).
2. Verify that a high speed serial card with a 16650 UART is
being used and the software drivers to support the extended
baud rate tables are installed.
Dial-Up Networking Difficulty
If Windows 95 Dial-Up Networking cannot talk to the Express
XR/XRT, check the modem configuration for the Express XR/
XRT. Ensure the bit rate for the DTE is set correctly. If the PC is
not equipped with a 16650 UART then the fastest DTE operation
speed is 115.2 kbps. Ensure the speed is not higher than the PC
and modem can support.
