MK2R+ (and all other microHAM interfaces) do not reflect handshake 
to the application.  If the K3 Utility requires handshake (like 
TenTec) it will not be possible to do firmware updates through 
a microHAM interface.  

With all of the interfaces (microKEYER microKEYER II, MK2R+), it 
will be necessary to set the radio type (Radio port in Router) 
to "None" while doing an update to prevent Router's polling from 
interrupting the update.
