Setting Up The Remote Modem:
1. In the Communications Setup dialog box, double-click on the second modem
icon (Figure 7-11). The Modem Setup dialog box for the remote modem
appears (Figure 7-14).
2. In the Remote Modem area, select your modem type. If your modem is not
listed, select the “Add” button to configure your modem. To do this, you must
know the AT commands for your modem. Refer to the documentation for your
modem.
3. In the Communications Mode area, select the communications mode (either
10-bit or 11-bit). The communications mode that you select depends upon your
modem capabilities. (The 10-bit and 11-bit communications modes are
described later in this section.) Both the local and the remote modem must
have the same communications mode. Click the “Configure” button.
4. The Configure dialog box appears (Figure 7-15). If you are using a predefined
modem there are no fields that you can edit. If you are not using a predefined
modem, you must enter the AT command string for your modem. Refer to the
documentation for your modem.
5. To test the configuration of your remote modem, click the “Program/Test” button
while the modem is connected to your local machine (programming device or
PC). This action transfers the parameters into a memory chip in the remote
modem.
6. Click the “OK” button. The Communications Setup dialog box appears.
