K3: AGC turns itself off while in config menu

[Julian, G4ILO]

I was adjusting the LIN OUT level while running CW Skimmer this morning and the volume from the K3 suddenly went very loud. When I checked, I found that the AGC had been disabled.

Upon investigation there appears to be an issue with software polling the K3 while in the menu. I can almost guarantee that the AGC will be disabled if I go into the menu while a program is connected and polling the K3. You might wait a few seconds or a few minutes before it happens, though.

I haven't had this occur when not in the menu. nor with the menu selected but no CAT software running. I'm using the latest beta (3.57) and a serial connection of 38400 baud.

I have not been able to duplicate this.

It's possible that one of the PC applications is colliding with  
another, or that one of them is using a direct DSP command in an  
incorrect context.

Application software can send an "MN" command to determine whether the  
K3 user has entered the menu. If they have, then the app can hold off  
polling.

I thought I got this to happen once with CW Skimmer running on its
own. But I have left it running for quite a time now without a repeat
of the problem.
