Why is CAT PTT control of a Peaberry on WSPR different than on WSJTX?

I have tried various virtual com port implementations in order to obtain CAT PTT control of my Peaberry/HDSDR combo on WSPR. All were unsuccessful. Finally in desperation I purchased two hardware USB serial ports and connected them with a null modem cable. Works great with WSJTX 1.3 but not at all with WSPR using the identical setup configurations. Why the difference? Any insight?
