Odd thing going on here with a denon.

All the RS-232 codes I've tried so far work... except for Sat.

I've tried the two different Denon RS-232 groups in the RS-232
library, along with the driver command for Satellite. I've also confirmed
that it isn't just a renamed version of the TV/Cable command.

Here is the code I'm using:

SISAT\r


SOLUTION:

The Denon display would read SAT/CBL when you manually switched to that input. I changed the RS-232 code to SISAT/CBL\r. Voila, success. The annoying thing then is that the driver potentially wouldn't work...

And a question: Could you potentially change the name of the various inputs and then have that reflected in the RS-232 codes you needed to use to select those inputs?
