[Elecraft] [K2] Rig Control Error

[Phil Kane]

Problem (described below) with the WSJTX program (the "home" of FT8)
trying to access K2.  I didn't get an answer on the WSJTX Yahoo group so
I'll try here.

Configuration:

Dell Laptop PC with iMic and RigBlaster Plus connected to Elecraft K2.
Both  the Elecraft and RigBlaster serial ports connected to the computer
are 9-pin "RS-232" wired ports and all drivers are current.

With PC running Windows 7, both MixW3 and WSJTX  2.0.0 using identical
CAT control and audio settings ran without problems.

After upgrading the computer to Win 10 with no other changes, MixW3 runs
properly but WSJTX 2.0.0 and 2.0.1 did not.  The error messages from
Hamlib are:

(Tune) "IO error while opening connection to rig"
(Test CAT)  "Communication timed out while opening connection to rig"

In additions, the frequency readout on the WSJTX UI has reverted to all
zeros.

Are there "permission" settings in Win 10 that didn't exist in Win 7?

Has anyone experienced this with Win 10 and found a solution?
