[WriteLog] K4 commands

[Alan Maenchen]

What I said earlier is not quite true.  Per K4 guru N6TV, the SWT commands
for the K3 don't work with the K4. However, other commands are backward
compatible.

To access the K4 DVR, use PB1;  thru PB8;

Here's what I have in my ini file:
[Elecraft_K3_commands]
Macro_18=PB1;
Macro_19=PB2;
Macro_20=PB3;
Macro_21=PB4;
Macro_22=PB5;
Macro_23=PB6;
Macro_24= PB0;

Note that PB0; will cancel any recording in progress. However ESC also
kills a recording immediately.
