Just a verification this is what he is trying to do. The Nomic is NOT in the
circuit for FSK. He is using the USB to serial device TX data out to key
FSK. I wrongfully assumed that Westmountain USB Serial adapters supported
'real' FSK like some other manufactures do. That is to say FSK without
EXTFSK.

Sorry to say, I normally skip posts not related to my hardware and did not
catch technical note - 101. <Grin>
As other Hams on various reflectors are reporting, my friend is having a
heck of a time with this <words deleted> Prolific interface and other radio
software. I was really disappointed to find out Westmountain's Rigblasters
use Prolific USB adapters.
Again thanks,
