To attach modem to Virtual COM Port Pair

The example below shows how to install modem driver when Fax Voip T.38 Modem is configured to operate with 3rd Party Virtual COM Ports. It is assumed that two Virtual COM Port Pairs already installed on your system. The first pair: COM10<>COM11. The second pair: COM12<>COM13. It is also assumed that First port COM10 from COM10<>COM11 pair and First port COM12 from COM12<>COM13 pair are connected to Fax Voip T.38 Modem, see in the chapter To configure Fax Voip T.38 Modem with Virtual COM Port Pair of this user manual. The Fax Voip 14.4K TAPI Voice-Fax Modem should be attached to Second port COM11 from COM10<>COM11 and to Second port COM13 from COM12<>COM13 pair.

To install modems do the following:

1.     Open Fax Voip T.38 Modem Control Panel.

2.     Click Ports and Modems in TreeView, check that the Use 3rd Party Drivers for Virtual COM Ports option is selected.

3.     Click <Modems> button.

4.     In the warning dialog click <Yes> to stop Fax Voip T.38 Modem Service (Fax Voip T.38 Modem application).

In our example you should attach the first modem to the Second port COM11 from COM10<>COM11 pair and the second modem to the Second port COM13 from COM12<>COM13 pair. Be careful when selecting ports. In the case of using third-party driver for Virtual COM Ports, Fax Voip T.38 Modem displays all ports existing in your system, except ports selected in the panel Select COM ports connected to Fax Voip modems directly (Fax Voip T.38 Modem "side" of Virtual COM Port Pair) and ports created by the native Fax Voip driver (if such ports exist in your system). In the case of our example, COM10 and COM12 will not be displayed.

6.      Click <Install Modem> button. To change modems configuration, administrator privileges are required.

7.     In the Modem Installing dialog box click <OK> to confirm modems installation.

Notes

• Fax Voip T.38 Modem installs Fax Voip 14.4K TAPI Voice-Fax Modem driver for modems. Compared with the standard modem driver, this driver provides support for Caller ID Number and Caller ID Name. Voice Commands are supported by the Fax Voip modem driver via TAPI and not only in the passthrough mode. To add modems using Phone and Modems option in the Windows Control Panel not recommended.
• Note that Fax Voip T.38 Modem does not update drivers for previously installed modems.
• Rebooting the operating system after changing the configuration of modems is not always necessary. Nevertheless, it is not recommended to ignore this step, because some programs may not properly interact with the modem drivers immediately after installation.

• For Windows Fax Service / Windows Fax and Scan users, when adding Fax Voip modems, you should manually configure the fax service with the newly installed modems. Alternatively, you can use the Configure Fax Service command in the Ribbon, see more details in the To configure Fax Service using Fax Voip T.38 Modem Control Panel chapter of this user manual.
