Re: Feedback using hex (DirecTV)

Due to the poorly designed protocol of the DirecTV box, I don't think
this will be possible. How hard would it be for them to just provide
the number in ascii...sheesh.

Anyway, you can try creating a feedback entry in the System Manager as
follows:
regex: \xF0(..)\xFF\xFF\xF4
capture group 1: serial join 1

Then create a text object on serial join 1 and see what it displays
when the channel status is parsed. Most likely it will convert to the
ascii equivalent (which is not what you will be expecting to see).

You must have your system setup to "maintain connection" for this to
work. And if all commands come back with a \xF4 delimiter, then set
the system EOM property to \xF4 (this helps split messages that come
in quickly).
