/*
* I. INITIALIZATION + OPEN SEQUENCE
* =================================
* ExtIoSDRFeatures()
* optional: inform ExtIO of SDR software's supported features
* ExtIoSetSetting()
* optional: previously saved settings are delivered to ExtIO
* call once with idx -1 to sign ExtIO that this functionality is supported,
* so that ExtIO may inhibit loading/storing any .ini
* InitHW()
* mandatory: initialize ExtIO. May do nothing!
* VersionInfo()
* optional: delivers SDR program name and version to ExtIO. Allows to check if some necessary
* functional extension is (not) supported by SDR program
* GetAttenuators()
* optional: show ExtIO, that SDR program supports controlling RF Gain/Attenuator(s)
* you should prefer this over determining SDR program's capabilities over VersionInfo()
* ExtIoGetMGCs()
* optional: show ExtIO, that SDR program supports controlling IF Gain/Attenuator(s)
* you should prefer this over determining SDR program's capabilities over VersionInfo()
* [ ActivateTx() ]
* optional: try's to activate Tx functionality
* SetCallback()
* mandatory: callback function pointer is given to ExtIO. ExtIO may inform SDR program of events
* using this callback interface and the extHWstatusT enums
* OpenHW()
* mandatory: prepare ExtIO for start .. or fail for any reason!
*
*
* II. START SEQUENCE
* ==================
* StartHW()
* mandatory: start processing
*
*
* III. WORK
* =========
* SetHWLO() and many other functions ...
*
*
* IV. STOP SEQUENCE (== 'undo' of Start sequence)
* =================
* StopHW()
* mandatory: start processing
*
*
* V. CLOSE SEQUENCE (== 'undo' of init + stop sequence)
* =================
* ExtIoGetSetting()
* optional: get and save settings for next time.
* call ExtIoGetSetting() before CloseHW() to get correct settings.
* do not call without súccessful OpenHW()
* CloseHW()
* mandatory: close hardware. Processing is not started again (with StartHW),
* unless OpenHW() is called again
* this function is called only when prior OpenHW() was successful
* take care not to free already freed or never allocated resources
