Com port output clattering / PTT control problem

I just developed a problem when setting up for JT-44/65 and FSK441. I
notice that the com port from the sound card to the sound card interface
( or even just to the XCVR ) causes the TX control relay to clatter. I
tried using RTS and DTR lines and the same problem. In other words, I
just cant seem to get a solid PTT signal out of the com port. Has anyone
experienced this problem ??
