What's in this update
minor bug fix and enhanced features added Fixed bug in DTMF regeneration, where transmitter didn't always key properly.
Added sanity check in Meterface programming, where it was possible to enter bad data which would cause the controller to freeze until watchdog timer would force a reset after 2 minutes.
Changed DTMF muting routines to deal with decoder falsing.
If enabled, DTMF now mutes on the 2nd digit instead of the 1st.
