This is going to kill me.
Fellas, thanks for the ideas, but still nothing.
First I tried Dave's idea of using the dtv control program on a windows
laptop. Tried this with all the command sets. New, old, D10-100 etc.
Tried both /dev/ttyS0 and /dev/ttyS1. So this seems to indicate either a
failed cable or a failed d10-300 box. (But, it could also be that this
program doesn't work with the D10-300? Yes? Or, I guess it could mean the
serial port is screwed up on my laptop).
Going with the former hypothesis, that the cable might be broken, I dug up
my volt ohm meter and checked the cable. It seems to be wired correctly.
That is, testing indicates it's wired like so:
Modular 4P4C adapter wiring DE9F Modular 4P4C Wire Color 5 1 Black 2 2
Red 3 4 Yellow
Ok, so next hypothesis. Busted receiver. Well, I bought two of these
things on ebay with the hope of eventually getting two pvr cards rolling.
So, I have another one laying around. Great, right? Another test.
Unfortunately, directv doesn't allow you to transfer the access card number
to new receivers. They make you buy a new card, $20! I wouldn't mind if I
knew this worked b/c I need the card anyways for two pvrs. But, it seems
like alot of money if I'm just going to have to go back to the drawing board
and buy d10-100s (vice 300s) or some other receiver.
But, wait. Maybe I could test the basic operations, e.g. turn-on, turn-off,
get channel etc., without actually having access to the satellite data
feed. This possibility got me real excited and I jumped out of bed, ran to
the basement to try it. Only to realize, that with the d10-300, you need
the software upgrade that comes down off the satellite. Ugh.
Have you guys had the same experience with Directv? $20 buckets just to
change receivers?
If I have to buy new receivers, which model would you recommend as the most
forgiving?
Again, thanks for all your ideas.
