Interfacing FTM100dr with APRSISCE via DigiRig

Greetings:

Has anyone interfaced an FTM100dr to APRSISCE via DigiRig?
I tried connected the FTM100 radio via DigiRig to the APRSISCE program.
When I enable the digirig port in aprsisce 32, the transmitter keys immediately.
Not sure how to solve this problem. I don’t see any RTS/CTS control in the port box, only 7/8 bits -odd/even.
Any ideas?
thanks

Tom,
Please post the screenshots of the configuration and we’ll go over relevant settings.
