What's in this update
fixed some bugs and added/changed several features Lots of little "tweaks" to improve overall performance Fixed bug in Port Activity timers, where they didn't time accurately Fixed bug in CTCSS Encode, where it didn't track COS properly Timeout Timers now program in seconds instead of minutes DTMF may now be disabled on a per port basis.
When disabled, that port will only respond to the Enable command or Macros 35 - 40.
This allows a port to monitor a comwork backbone and ignore most commands.
By allowing certain macros to be called when DTMF is disabled, it is possible to link/unlink that port without allowing access to other commands from that port DTMF access may now be selected on a port-by-port basis, to require CTCSS or not require CTCSS Alarms changed.
They no longer call their own unique speech messages but rather may be programmed to call a macro or an Auxiliary Audio Input.
This provides much greater flexibility The ability to play any voice or CW ID from within a macro Unlock codes may be reset to factory default without affecting any owner custom programming Moved port assignments for speech from the scheduler programming to macro programming, since the scheduler calls macros in the first place Ability to rename macros (you can now assign custom command codes to each of the 40 macros) Fixed bug where courtesy tones didn't always wait for current command acknowledgement before being sent Fixed bug in CW speed selection where the cw speed wasn't always accurate Fixed bug in courtesy tone delay time.
Sometimes the programmed delay wasn't accurate Added capability o reset the unlock code without wiping out all custom programming by installing a temporary jumper on Port 3
