I've used the Quatech QSP-100. One item has me confused. You say that the
Quatech ports are COM3-6. I believe that the software only
allows them to load as COM5-8. Was anything done to reconfigure these to
COM3-6? If so, you might try to reconfigure them again, only
as COM5-8. In all my experience with the Quatech, it always loaded above COM4
(once, it even loaded as COM6-9)
I hope this might give you a clue to use.
