CAT problem using same comport for PTT and CAT

Greetings fellow whisperers.
Is anyone sucessfully running CAT and PTT using same COMport? My problem is that the CAT (freq control) won't work, but PTT works OK. CAT fails because the DTR signal goes high when WSPR opens COMport to send CAT commands, which causes radio to go to TX and ignore CAT commands. If I disconnect the PTT signal from the radio, CAT works correctly. (but no TX of course)
My config is FT1000MP (original model) using COM3 running WSPR ver 2.0. Other radio control programs work perfectly with this same configuration and same equipment, but not WSPR.
