[mythtv-users] Serial control of RCA DirecTV box -- should I bother?

[Abigail Smith]

Perhaps just use "cu -l /dev/.... " to access the port and see if there's data?  You could also try doing a "stty < /dev/<serial port>".  If there's a connection you'll get a response similar to:
   
  $ stty < /dev/console
speed 38400 baud; line = 0;
-imaxbel
-echoe -echok -echoctl -echoke

   
  Hope this helps,
   
  Abby

  We'll all be happy to hear the answer once you find out. :) Since you've got a standard serial port, it will be about a $4 investment to find out. Probably just need a null modem cable. 

  

Ahhh -- It's a noob's life for me. If I did  try and it failed, then it would be impossible to tell the difference between a compatibility issue and an operator error. 

But for kicks -- let's say I did make a serial to serial cable and connected the serial port on the RCA to the PC's serial port -- then what? I have no ideal how to determine if there is life on the port -- "statserial" perhaps? 

Do you think the script for the Rj 11 would work for the 9 pin connection?

You should see a difference between no activity (timeout) and bad information (unrecognized string returned). I suspect it will work since the STB probably doesn't care which connection is being used and will treat commands from either of them the same. Your mythtv box will have no idea (or care) what kind of connector is on the other end as long as the expected response comes back.
