Changing The Parameter Settings 5-4
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:
1 Ensure that your computer’s COM port and
communications software support 230.4 Kbps.
2 Send 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”.
3 Change 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:
1 Launch your communications or terminal emulation
software.
Be sure your communications software is in terminal mode.
2 Be sure the 3C882 ISDN modem is in command mode
(sometimes called local mode or terminal mode) so that it
interprets your commands.
When your computer is powered on, the 3C882 ISDN
modem automatically starts in command mode. If you have
recently used the 3C882 ISDN modem to make a call and
have not yet disconnected, type +++ to switch to command
mode.
