Using the D2–DCM with Modems
Data Communications Module, 2nd Edition, 2/03
Using Direct SOFT32
Direct SOFT32 uses Telephony Application Programming Interface (TAPI) for
modem configurations. The TAPI protocol allows applications to control modems or
other telephony devices for operations such as dialing, answering, or disconnecting
a connection. With the TAPI protocol, all of the modem support is centralized by the
Windows operating system.
By using the TAPI interface, you will use the Windows modem setup utilities to
configure the modem. Configuring the modem in this matter should simplify the
setup process and allow you to select the most recent drivers for your modem.
If there is an existing modem connected to your PC for Internet or fax use, the
modem setup will have to be changed. Some of the features will have to be disabled
in order to communicate to the PLCs. To avoid making any changes to the existing
modem configuration, you will need to install the same modem a second time.
Windows will change the name by adding a number to the end i.e., “
modemname#2
”
each time you add the same modem to your PC. Refer to your PC and/or modems
installation manual for additional information on setting up your modem.
The first series of examples were performed in Windows 2000 and will illustrate how
to configure the modem connected to your PC. The examples may differ depending
on your Windows operating system.
1.
Install the modem if not already installed. Refer to the modem’s
documentation for installation information. If the modem is to be used for
other devices you will need to install it a second time.
2. Once you have successfully installed the modem, you will need to edit its
properties. In the Windows
Start
field, select
Settings > Control Panel
