Kelly,
Try N1MM rotor control. I cannot control my rotor (Alfa Spid) with DX4WIN
but works FB with N1MM.

That's a good point, however, the rotator controller does not respond
to the commands I send it through hyperterm. Clearly, I could have
entered the wrong commands, but the mere fact that I can't get the
rotator to respond correctly OR output printable characters OR respond
to CAT programs which has native support for this controller suggests
that something isn't right :-)
I'll log the non-printable characters tonight and see if they make
sense. Thanks for the suggestion.
