Anyone ever use the RS-232 codes in the Mega with the Marantz SR8002 or similar? For some reason I am getting absolutely no response. I made a test config with the codes for a few commands, power on , inputs, etc, se the command for port 1 which the CM-232 and null modem adapter are located, and nothing. Strangely all the emitters are blinking off (don't know if that is normal since I am not sending out any IR and have the port 1 assigned to RS232).

Anyone have any ideas or know if the codes are bad? I just used a power sensor and mono plug into the IR in jack and it works fine, but would like to get this operating over 232. Any insight?

Thanks
Jimmy
