You can use the com port on the rigblaster, but if your like me - I use the com port for rig control ( CAT fxn ) on my ft-920. Too bad dx4win will not key the ptt via Cat commands. Mix W will do this and so will mmsstv. I had been using a lpt ( printer port ) interface to key the ptt while maintaining the line between the computer and my rig. This works fine with dx4win, It can also be used to send cw via the keyboard if you set it up correctly.
