P3-SVGA Programming bug

[tomb18]

I came across a bug which will most likely put my efforts for a windows p3 application on hold:  It concerns the markers.  I first found this in my program itself, but I can reproduce it with RealTerm which is an async terminal program.
Basically, when it works  it goes like this: (I alternate the frequencies manually to show an effect)

I enable the marker: #MKA1;
The correct marker frequency shows up on both the SVGA and P3.

I then issue a #MFA+00018100000; (for an example)
This shows up on both displays
I then issue a #QSY1; which is supposed to put the K3 at the marker frequency.
I then issue a #MKA0; and the markers turn off

This works 3 maybe 4 sometimes 8 times then the following happens:

I enable the marker: #MKA1;
The correct marker frequency shows up on both the SVGA and P3.

I then issue a #MFA+00018100000; (for an example)
This shows up on both displays

I then issue a #QSY1 and now things change drastically.

The SVGA screen shows the marker frequency as the original frequency before the #MFA+00018100000
The P3 Screen shows MRK A: 0 (not the frequency)
and the frequency does not change.
When the #MKA0 is issued, the P3 marker is gone, but the " MKA Frequency" text on the P3 remains.

At this point, it seems to never get better, unless I fiddle with the controls on the P3 itself.

Any ideas of a work around?  It's really too bad, I'm almost set to go.

Thanks for any help.

Found a work around.  Instead of #QSY1 I issue a FA + frequency to the k3.  Works the same.

You could also use the commands #MFA 0 and #MFB 0, which, according the
programmer's guide will set the markers to the K3 frequency on the corresponding
VFO.

Did you try that?
