FOOT SWITCH SEQUENCER
Additional functions can be associated with the foot switch (or hand mic PTT). micro2R recognizes when
the foot switch is closed (pressed) or open (released).
micro2R can mute or
block serial port CW,
FSK, PTT and audio when
the foot switch is
activated. Each of those
inputs can be selectively restored when the foot switch is released or can remain muted until all PTT inputs
are released.
Mute serial CW - if checked, virtual port CW (DTR or RTS) output generated by an application program will
be muted while the foot switch is closed. If Restore serial CW is checked, CW will resume when the foot
switch is released (if it has not already ended). If Restore serial CW is not checked, application generated
CW will remain suppressed until the application releases PTT.
Mute serial FSK - if checked, FSK generated by an application will be suppressed while the foot switch is
pressed. If Restore serial FSK is checked, FSK will resume when the foot switch is released (if it has not
already completed). If Restore serial FSK is not checked, FSK will remain suppressed until the application
releases PTT.
Restore serial PTT and audio - if checked, application generated serial PTT will be restored and audio
routing will return to the "serial PTT" setting when the foot switch is released. If Restore serial PTT and
audio is not checked, audio will only return after the application releases PTT.
