Also make sure BOTH radios are in the same mode.
There are 2 types of data transmissions: Slow mode, as supported by most D-Star radios, and DV Fast Data as supported by IC9700 and 705...
I ran into this using a IC7100 with an IC9700, whara the 7100 ony supported slow mode and the 9700 being set by default for fast data..

Troubleshooting D-Rats:
Two computers running d-rats can have a NULL modem cable connected between them instead of connecting d-rats to a radio.
If you have only USB to radio cables, that will be harder to rig up but may still possible, but would take wiring up some jacks to cross the data lines depending on what the data port on the radio now looks like.
USB Driver updates on Microsoft Windows can stop USB adapters from working.
Since you report that the you are getting some communications, that indicates it is probably not a USB adapter issue.
Baud-rate, and character size, parity and stop bits should be checked, but I also do not think that is the issue.
Character size should be 8 bits, parity should be none, and stop bits should be one.? Baud rate depends on the radio.
