Cool, will the RS232 port broadcast status info, like the DSP5000 / 3100's do? (i.e. volume / source)

I've been chipping away at automation, currently have a 12V trigger (G96 - active when I select a source that needs the TV powered/rear room lights off) and the RS232 port monitored on my DSP5000's to read which source selected and current volume. (I did have basic control as well, but lost that code when I switched processors and it's going to be a pain to recreate).

I don't suppose there are any lines on the RS232 port that can be used to determine whether 'standby' is selected?

Thanks for the info,
Matt
