The pin_changed event from serial port is being queued while the
eventhandler is busy, but how do I change it so that the new event is
ignored instead while eventhandler is busy (I want to eliminate switch
noise)?

Thanks

OK - found a solution - I just disabled the event as soon as entering the
handler and enabled it at the end again - works well!

This is not necesarily a solution it depends on how the event is being
dispatched.

The event could be dispatched concurrently on multiple threads in which case
you code could still end up being re-entrant.
