hey guys!!

Well, I have finally gotten a DirecTV satellite receiver with serial 
interface (a Uniden as it were).. When I tried to get sony.pl going from 
http://tarek.2y.net/myth/sony.pl , it did not work properly.. I went back 
to the original file, which is from http://www.hitchhiker.org/dss , and got 
it.. it worked.. So, I chopped it down a smidge, and made it a command line 
script.. Here are the differences between this and the previous sony.pl 
(available at http://tarek.2y.net/myth/sony.pl.old):

1) The default serial port of the script is serial port 1 (ttyS0)
2) It sleeps between each send for approximately 0.1 seconds, which 
prevents a bug that had been happening on mine and other receivers in which 
it would send the first character and then jam.
3) It actually works.. at least on my uniden : )

I am *completely* open to any suggestions / bug reports / etc. For more 
information on the scheme underlying this puppy, or to try to control your 
dtv receiver from windows:


Now the fun *really* begins : ) Thank you all : )
