 * Description:
 *    Sejin IR Keyboard and RS-232 Receiver Defines
 *
 * NOTES:
 *
 *    - Keyboard sends 4 byte packets per character/event
 *
 *    - IR Receiver has LEDS (CAPS_LOCK, SCROLL_LOCK, NUM_LOCK) which
 *       require transmitter to send data -
 *
 *       - IR Receiver RESET Command:
 *          - Tx: - 0xFF -
 *          - Rx: No response (until SelfTest command sent)
 *
 *       - IR Receiver SelfTest and Revision Request Command:
 *          - Tx: - 0xF3 -
 *          - Rx: - 0xAA (self-test OK) or 0xFE (fail)
 *                - revision byte (0xXX)
 *
 *       - IR Receiver LED Command/Control Bits:
 *          - Tx: - 0xEx -
 *                - x is any combination (OR) of the following:
 *                   - CapsLock   - 0x04 -
 *                   - NumLock    - 0x02 -
 *                   - ScrollLock - 0x01 -
 *          - Rx: No response.
