RE: TI-H: Infrared control


Well, I have my share of universal remotes, but eventually I would
appreciate testers.
The range of the port seems to be no more than a foot or so in somewhat
lighted situations. Apparently infrared works much better in dark
situations. But that is not really the problem anyway.
With regard to regular remote controls being able to communicate with IrDA -
well, the CE device can read from the remote, and only when a remote button
is pressed, so there is *something* going on there. The question I have is:
how do I interpret that something.

Here are some samples:
Sony stereo:
-64 -64 -32 -64 -32 0 0 0 -32 0 -64 0 -32
-64 -64 -32 -64 -32 0 0 0 -32 0 -64 0 -32
-64 -64 -32 -64 -32 0 0 0 -32 0 -64 0 -32
-64 -32 -32 -64 -32 0 0 0 -32 0 -64 0 -32
-64 -32 -32 -64 -32 0 0 0 -32 0 -64 0 -32
-64 -32 -32 -64 -32 0 0 0 -32 0 -64 0 -32
-64 -32 -32 -64 -32 0 0 0 -32 0 -64 0 -32
-64 -32 -64 -64 -32 0 0 0 -32
(tabulated by me - weird that it is all the same, I pressed random buttons)
Panasonic TV:
0 112 -4 112 60 14 -16 56 30 7 112 60 -2 112 60 30 7 112 60 30 7 112 60 30 7
112 60 30 112 -4 -16 -16 -16 112 60 -2 112 -4 -16 -16 -16 112 -4 -16 0
112 -4 112 60 14 112 60 30 112 60 30 -1 112 60 14 112 60 30 112 -4 112 60 30
112 60 30 7 112 -4 -16 -16 -16 112 60 -2 112 -4 -16 -16 -16 112 -4 -16 0
112 -4 112 60 14 112 60 30 112 60 30
(These are simply the raw data read in from the IrDA port (treated as a
serial port, standard Win32 CreateFile(), ReadFile() etc.)

One thing I am considering: Maybe I am not reading from the port fast
enough? These devices have limited speed, but who knows. Maybe it is too
slow because I am wasting time refreshing the display each time?

Again, any help and/or information is appreciated,
