Difficulty with 230.4 kbps operation.
If the Express 3000 does not work when the DTE rate is set (inside
Windows) to 230.4 kbps, verify the following:
1.
DIP switch 1
on the back of the Express 3000 is set to
Off (up)
.
2.
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.
1.
If Windows 95/98 Dial-Up Networking cannot talk to the
Express 3000, check the modem configuration for the
Express 3000 and ensure the bit rate for the DTE is set correctly.
2.
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.
