[Dx4win] Can't Spot A QSX Freq On IC-756Pro2

[Toby and Ira Stoler]

Anyone have any ideas?  I cannot get the radio (IC756Pro2) to spot a qsx
frequency when operating split.  As you can see from the paste below, the
program doesn't seem to be able to read the sub-vfo.  If a spot has a qsx it
loads both vfos and sets split properly, just not when I spot while split.
QSX frequency is blank (0) and spot frequency is shown as which ever vfo is
currently selected.  By the way, problem appears the same with V5 or V6.

Here's my set up:

IC756Pro2 - Radio on COM4: at 9600 baud (COM4 is USB expansion port but
tried on COM1 with same results)
Radio and program set to address 5C(hex) which is the default for the 756.
The Pro2 default is 64(hex).
Icom transceive setting is off.  I am using a third party RS232 level
converter not a CI-V.

Here are the tests I ran and the test data results:

VFO A=14195.00, VFO B=14205.00, SPLIT=ON, VF0 B=SELECTED
