4.11.1.3 +MKPD, Auxiliary Keypad Control
This command enables accessories to control the press and release of key presses. This command uses virtual keycodes, which
may not be supported by all members of the g20 product family. If a key is not supported by a g20, the g20 returns a +CME
ERROR: indicating that error 25 (Invalid character) has occurred.
Only a single key may be pressed at a given time. Sending in a new key press without releasing the previous key results in the
previous key being automatically released.
