Description This command returns any buffered key presses via the RS-232 inter-
face. The host system must be set up to receive key codes. When the
display receives this command, it will immediately return any buffered
key presses which may have not been read already. If there is more than
one key press buffered, then the high order bit (MSB) of the returned key
code will be set (1). If this is the only buffered key press, then the MSB
will be cleared (0). If there are no buffered key presses, then the returned
code will be 0x00. Please note that to make use of this command, the
“Auto Transmit Key Presses” mode should be off.
