What do you expect us to tell you? That it seems to be a TCP based communication with a STX byte as start of message indication, then a text string containing some command and then an ETX byte to indicate the end of the message?

Did you notice the little prefix on the left border of the string constants? x means that it is in binary display mode while n indicates normal text mode.
