Adding a Virtual Modem
To add Virtual Modem, do the following:
- Select Add/Remove Modems tab in Configuration Panel.
- Select the serial communication port which virtual modem will be assigned to from “Modem serial port” combo-box. Please, note that you will not be able to select port which is already in use.
- Specify TCP port which will be used to accept incoming connections on. You may type any number from 1 to 65535, however, make sure that it doesn’t interfere with other network services (DNS, Mail, HTTP, SMB, etc.).
- Click “Add modem” button.
- On successful creation, you will see confirmation message:
Once the virtual modem is successfully added, it may accept incoming calls.
To be able to initiate the call, you must specify remote host IP address and port (i.e. configure it as a client).
