Some K4 switch functions will be mapped to K3/K3S equivalent SWT/SWH switch codes
for backward compatibility. (List TBD.)

TB$

GET format:

TB$;

RESP format:

TB$trrs; where <t> is the number of queued transmit characters still to be

sent (from KY packets; up to 9, and 9 if higher than 9); <rr> is the count of available
receive characters for VFO A or VFO B; and <s> is the text string itself, which can include
semicolons, etc.
