Not sure exactly what you're describing in the first example, but I believe the answer is that the commands are serialized. I'm not sure just how clever LP-Bridge may be about deferring or discarding commands that can't be executed because the rig is in a state that prevents it. This probably happens all the time, without LP-Bridge, when the rig is transmitting and the logger wants to change some parameter that can't be changed during transmit. The command is essentially ignored in that case.
The second example is straightforward. If a program sends a frequency change command, the second program won't be aware of it unless it polls or sends an appropriate status query command. But this is no different from the scenario where the user manually twirls the VFO dial. That's why most programs that need frequency information either poll or issue commands to get status when it's needed. 73, Dick WC1M > -----Original Message----- > From: Dick Dievendorff [mailto:die...@comcast.net] > Sent: Wednesday, December 23, 2009 5:38 PM > To: wc1...@gmail.com; 'Julian, G4ILO'; elecraft@mailman.qth.net > Subject: RE: [Elecraft] K3 needs survey -- firmware and application software > > If one program opens a menu, and another program sends a VFO "UP" command, > is the second program's UP command deferred somehow because the first > program has a menu open? > > If one program sends a frequency change command, will the second program be > aware of that new frequency without polling? > > My point is that the programs must cooperate, and that's not always > possible. > > Dick > > > -----Original Message----- > From: Dick Green WC1M [mailto:wc1...@gmail.com] > Sent: Wednesday, December 23, 2009 2:31 PM > To: 'Dick Dievendorff'; 'Julian, G4ILO'; elecraft@mailman.qth.net > Subject: RE: [Elecraft] K3 needs survey -- firmware and application software > > Dick, > > LP-Bridge acts as a traffic cop that allows multiple programs to share the > K3 COM port without interfering with each other.
