Do the lights blink on the side of the IRF-6 when you press the button on the T2 that corresponds to the RS232 command?

Somtimes you have to put an /x or a //x before the command for it to work just like you would with a hex command so it could be /xPWRON\r or //xPWRON\r , but this is not always the case and might not work.
