To access the 3C882 Configuration dialog box, Autobaud must be enabled. If the baud rate is set to a specific rate, you will not be able to access the Configuration dialog box. Before setting a specific baud rate, ensure that the Configuration dialog box parameters are set appropriately.

To set the baud rate to the maximum of 230.4 Kbps, do the following:

1Ensure that your computer’s COM port and communications software support 230.4 Kbps.

2Send the command AT $B 230400 to the 3C882 ISDN modem.

For instructions on how to send AT commands, refer to the section “Changing The Parameter Settings”.

3Change the setting of your application program to 230400 bps.

This completes the procedure to change the baud rate to 230.4 Kbps.

Changing The Parameter Settings

To change parameter settings:

1Launch your communications or terminal emulation software.

Be sure your communications software is in terminal mode.

2Be sure the 3C882 ISDN modem is in command mode (sometimes called local mode or terminal mode) so that it interprets your commands.
