A command is a simple text string. After receiving a command, the V-Tap always
sends back a reply string. The following commands are recognized by the V-Tap:

CLOCK
CLOCK,<date>,<time> [set clock]
BUSY,<line1-31>
START,<line1-31>
STOP,<line1-31>
PAUSE,<line1-31>
RESUME,<line1-31>
PLAY,<line1-31>,<file> [playback WAV file] OK- or NOP-<id>:PLAY,<line>
<id> is the V-Tap ID, the same as characters 17+18 in the file name above.
<date>,<time> has the format "dd-mm-yy","hh:mm:ss" (14-12-18,16:35:07).
A recording command for a non-busy channel sends a "NOP..." message back.
An unknown or bad command sends an "ERR.." message back.
