Phone Number to Host Mapping
If your modem application dials using a phone number, you can add an entry in the Phone Number to
Host Mapping window that can be accessed by all serial ports configured as Virtual Modem. You
need to enter the phone number sent by your modem application and the Terminal Server IP address
and TCP Port that will be receiving the ’call.’ The Terminal Server supports up to 4 entries.
The following buttons are available:

Phone Number
Specify the phone number that your application uses to connect to the remote

must be entered in the exact way it is issued by the application. For example, if
you enter 555-1212 in this table and the application sends 5551212, the
Terminal Server will not match the two numbers.
