Digi One SP Realport will not communicate through com port

Digi One SP I have connected the device via IP to a VM running MS Server 2012 R2. It recognizes the device but will not communicate throught the com port to send messages to the Pager system

Do you see data if the loopback plug is inserted?

If you are able see the data with the loopback plug inserted, I recommend focusing on the cable pin-outs used to connect to the pager system.

If the loopback data is not seen, make sure the serial port profile on the Digi One unit is configured as RealPort.

If it is still not seen, try running the loopback test bypassing the driver:
