3-30 CHAPTER 3: CONFIGURATION FOR AN IBM-COMPATIBLE PC RUNNING WINDOWS
Setup for 230Kbps
The 3C882 ISDN modem allows for transfer rates of up to
230.4 Kbps. Note that some computers require the
installation of additional hardware, such as an accelerated
serial port card, to take advantage of this higher speed.
There are two setup scenarios covered:
■ 230K setup for Windows NT 3.5.1
■ 230K setup for Windows 95 and Windows NT 4.0
Setting up 230K for Windows NT 3.5.1
These instructions require prior installation of the modem.inf
driver, which is installed as part of the initial setup procedure.
Refer to “Setup Using Windows NT 3.5.1 RAS” earlier in this
chapter for assistance.
1 Ensure that your computer’s COM port and
communications software support 230.4 Kbps.
For instructions on sending AT commands, refer to the section
“Changing the Parameter Settings” on page 5-4.
2 Using terminal emulation software send the command
AT
$B 230400
to the 3C882 ISDN modem. This will set the
baud rate to 230.4 Kbps.
Once the baud rate is set to a fixed amount you will no longer
be able to access the Configuration dialog box to make
changes. Refer to “Restoring the 3C882 ISDN Modem to
Autobaud” on page 8-9 for assistance.
3 Save this setting by entering
AT&W and press return.
Next you must install the 230K driver to take advantage of
the speed increase.
