Send Data over External Serial Interface with Wake-Up

After the external serial interface has been switched on, it is possible to send data to a connected
device (all bytes hexadecimal). This command supports wake-up commands over a serial optical
interfaces (e.g. 0101010... bit streams using the selected baud rate). To realize a wake-up command
the given byte CC (see below) is DH:DL times sent over the serial interface before sending the data
frame. Between wake-up command and data frame a 50 ms pause is introduced. Using e.g. 0x55 as
byte CC a 010101... bit stream of variable length can be realized. The wake-up byte is always sent
with no parity bit.
