[Elecraft] K3 command mode default k30 k31

[Don Wilhelm]

Joe,

I beg to differ.  The K3 does provide the information on the command 
state via the 'K2n;' command and the 'K3n;' command.  The K30 state is 
clearly documented as the default.

I repeat, any software that needs to issue K31 commands must assure that 
the K3 is capable of accepting those commands.

This is a task for the programmer who says they support the K3 command 
set. 

IT IS NOT A MATTER OF NOT CHANGING THE STATE OF THE RADIO - the 
situation is that the software is trying to issue a command that 
requires the K31 state.  The command cannot be received if the radio is 
not in the K31 state - so either the software must use an alternative 
method or it must set the K31 state.  If the software must restore the 
radio to the K30 state afterwards (to be "good programming") than by all 
means, issue the K30 command at the end of the process.

That fact that other radios 'do it differently' is not a reason for 
software which supposedly supports the K3 command set to make 
assumptions about the state of the K3.

I do come from a long background that says any software that makes 
assumptions (without checking) is faulty programming.
