Re: Feedback using hex (DirecTV)

That's no fun DIRECTV...

The good news is that the feedback is working, however, as you said
I'm getting the ascii output for the text. So for channel 77 I get a
capital "M". I know that the iRule (iRuleathome.com) will be coming
out soon for the iPhone/iTouch and will be able to do this. An chance
that commandfusion will support it too?

I don't understand why DirecTV doesn't have good for support for
RS232. I have two H23's and two HR23's and all the documentation for
RS232 seems to stop at the HR20. However, all the commands still for
the H23 and HR23. Don't they know that there are people that want to
build automation systems around this stuff? I also wish that they
wouldn't have canceled the work on the HDPC-20 for Windows MCE.
