Remote Control Commands
Remote control commands may be issued to the SD5902 singly, or combined in a string with other
commands. The string may optionally be terminated with an ASCII linefeed character (hex 0A, decimal
10), and commands may optionally be separated by the semicolon character ‘;’. The SD5902 is not case
sensitive so combinations of upper and lower case are acceptable.
