I have been trying to get my MSC-400 to communicate with my Yamaha RX-V1500 with no success. I was wondering if anybody has made this work. I set the parity and baud to Yamaha's specs and am using a null modem. Here are some examples of the strings that I tried that I got from a different thread.

serialstring "DSP: Game" "\x0207EF2\x03"

serialstring "DSP: 7ch Stereo" "\x0207EFF\x03"

serialstring "DSP: Pop/Rock" "\x0207EF3\x03"

serialstring "DSP: Classical" "\x0207EF5\x03"

serialstring "DSP: Mono Movie" "\x0207EF7\x03"

serialstring "DSP: Var Sports" "\x0207EF8\x03"

serialstring "DSP: Spectacle" "\x0207EF9\x03"

serialstring "DSP: Sci-Fi" "\x0207EFA\x03"

serialstring "DSP: Adventure" "\x0207EFB\x03"

serialstring "DSP: General" "\x0207EFC\x03"

serialstring "DSP: Normal" "\x0207EFD\x03"

serialstring "DSP: Enhanced" "\x0207EFE\x03"

Any hints on how to make this work. I thought I would try on my own because I am sick of waiting for URC to put Yamaha's codes in their database.
Thanks,
Chad
