[mythtv-users] DirectTV external tuner help

[Gavin Haslett]

Be aware also that unless you request it from DirecTV, your serial port may not even be enabled. I had to specify to them that I was planning to use a Tivo and they enabled it for me over the phone.

What does did not work mean?  Did you get an error?  What happens when 
you try the script from the command line.  Does the serial port in the 
script match the one you have the receiver connected to?  By default the 
script uses /dev/ttyS0.

Probably not, as you set the devices to 777.  There are so many other 
things it could be like: cable is wired wrong, script is not the right 
one for that receiver, is the script set to the same device you have the 
directv receiver plugged into.  BTW, on some (most?) Linux distros the 
dev entries are created dynamically and the permissions may be reset 
after a reboot.  So don't reboot (this isn't Winblows after all).

In this case shouldn't be a problem.

I have a different receiver (RCA DRD-435) and use a different script 
(rca_control.pl), but this link may help you:
