WINMOR TNC Revision History


Revision	Date		Description/changes

1.1.1.0		May 8, 2010	Release of 1.1.0.6 

1.1.0.6				Added Connection State IRSModeShift to WMLinkProtocol.ProcessControl for Case Idle to eliminate hang if Answer to ISS Mode shift request results in an IDLE from ISS.
				Update of Help and Help index

1.1.0.5				Fixed failure to update capture state on WMLinkProtocol.SendNCar8PSKTCM.

1.1.0.4				Modify tmrPoll interval back to 32 ms with slow segment every 64 ms.

1.1.0.3				Modify exception logging if aborting playing sound wave or stuck PTT in WMInterface.tmrPoll
				Modify Sound card restart trip limit from 10 to 12 seconds. 
				Modify placement of dttLastSoundCardCapture=Now in WMInterface.ProcessCapturedData
				Remove nested Try/Catch in WMInterface.ProcessCapturedData

1.1.0.2				Move set of RecState = Transmitting to in front of every call to PlaySoundStream
				Put logic in WMInterface.ProcessCaptureData to not update water fall in Transmit mode.
				Add synclock objPlaySoundStreamLock in WMInterface.PlaySoundStream

1.1.0.1				Removed condition of Not PTT in test for restart in this statement of tmrPoll.Tick
				"If Now.Subtract(dttLastSoundCardCapture).TotalMilliseconds > 10000 And blnEnableCaptureRestart Then"

1.1.0.0		April 22, 2010	Release of 1.0.9.2 

1.0.9.2		April 20, 2010	Set RestartRecovery to reset dttLastReply to avoid a timeout after sound card restart.
				Changed sound card timeout trigger back to 10 sec (was 5) to see if it reduces the number of restarts.
 				Changed WMInterface.ProcessCapturedData to reset dttLastSoundCardCapture whenever bytCaptureData.length > 0 

1.0.9.1				Change RestartCaptureDevice to insure playback buffer is not playing and NOT reset WINMOR connection state.
				(need to verify this will recover a session)
				Modify WMInterface.tmrPoll to 20ms(was 32) with sub tick every 100ms (was 64). Move some functions to 100 ms poll. 
				Reduce timeout trigger for RestartCaptureDevice from 15 to 5 seconds.
				Try new Search for leader algorithm using WMDemodulate.SearchForLeaderTone3 which uses the Goertzel algorithm for non integer bin tone detection (more sensitivity and accuracy). Tests indicate Goertzel algorithm works and is more accurate using non integer frequency bins.
				Increase margin in GetRecycleTime to 300 ms (was 200 ms).
				Fixed non updates of dttLastGoodDecode in WMLinkProtocol (triggers use of Goertzel algorithm) 
				

1.0.9		April 17, 2010	Replace synchronous queue Play wave stream mechanism with call to (now Public) PlayWaveStream() in WMInterface. Eliminates tmrPoll ambiguity and latency. 
				Remove EarlyPTT function and call (no longer needed with above).
				Include automatic 40 ms Dwell in KeyPTT when going from Keyed to unkeyed.
				Added clear of blnIDSent to Initialize (caused extra data repeat on startup).
				Fix WMLinkProtocol.SendCWID to not show "-ssid" on transmit label.
				Use Global Call sign filters to check valid call sign for registration.

1.0.8.0		April 15, 2010	Release of version 1.0.7.2

1.0.7.2				Add additional down shift mechnanism in WMLinkProtocol.GearShiftAlgorithm based on time since last positive ACK response.  Should force downshift it > 45 sec since last dttReply (positive ACK).
				Add provision in WMLinkProtocol.CreateOBDataFrame to shift to 2Car4FSK mode if Robust = true, and > 30 seconds since last positive ACK.
				Make small tweak in BusyDetect to dblAvgBaselineFast = .5*(dblAvgBaseline + dblAvgBaselineFast) [was = dblAvgBaseline] to minimize BusyWide sensitivity to static crashes.
				Fix comparison in RestartCaptureDevice that did not force upper case.
				Make changes to accomodate large type fonts.

1.0.7.1				Changed measurement of turn around latency to occur only on initial response to data frame.
				Changed GetCycle length to use intMeasuredTurnAroundLatency
				Base intIDCycle calculation on intMeasuredTurnAroundLatency and recalc in MeasureLatency
				Initial intMeasuredTurnAroundLatency set to 1500 ms (a safe value)...normally measured latency will be 700-1200ms.
				Added mechanism for EarlyPTT upon initial connect request to insure proper PTT keying. Only affects initial answer ACK.
