Click the Start button and type in ‘cmd’ in the Search box and hit Enter. A command prompt application will be started. At that prompt now type in ‘telnet [ipserver] [portnumber]’ and hit Enter.
[ipserver] represents the ip address or computer name of the iPoint server machine. The [portnumber] represents the port number that is used for your iPoint communication.
If the command returns an empty screen, then the communication is allowed and should be operating correctly. Proper communication is not allowed when you get error messages. Press F6 to close the connection. In case of a successful connection, you will now see error messages when ending. These errors and messages can be ignored.
