The PollingTransceiver class was not dealing with frequency change commands correctly when the mode was not specified. Improved some diagnostic messages. Only leave transmit mode when PTT is seen to drop. Merged from wsjtx-1.4 branch. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@4886 ab8295b8-cf94-4d9e-aec4-7959e3be5d79

// update and caching of a transceiver state.

// Collaborations
|

//
|
|
// Implements the TransceiverBase post action interface and provides
|
|
// the abstract poll() operation for sub-classes to implement. The
|
|
// pol operation is invoked every poll_interval milliseconds.
|
|
//
|
|
// Responsibilities
|
|
//
|
|
// Because some rig interfaces don't immediately update after a state
|
|
// change request; this class allows a rig a few polls to stabilise
|
|
// to the requested state before signalling the change. This means
|
|
// that clients don't see intermediate states that are sometimes
|
|
// inaccurate, e.g. changing the split TX frequency on Icom rigs
|
|
// requires a VFO switch and polls while switched will return the
|
|
// wrong current frequency.
