I have been searching for an answer to my channel changing woes with my new DirecTV H20 receiver. I have read over the wiki page at: <a href="http://www.mythtv.org/wiki/index.php/Controlling_DirectTV_D11_via_USB" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
http://www.mythtv.org/wiki/index.php/Controlling_DirectTV_D11_via_USB
</a> and I've even helped a buddy to get this working on his setup with a DirecTV D11 receiver. No matter what combo of the parameters I use, I get the timeout and excessive retries problem. I have tried to verify the setup and cabling is with the following tests/actions:
<br><br> - plugged usb to serial into an open usb port on the mythbox, shows up as /dev/ttyUSB0 and in dmesg as a PL2303 usb to serial adapter.<br> - plugged usb to serial into open usb, serial end of same cable into null modem cable, null modem cable into my first COM port. I ran cat /dev/ttyUSB0 in one xterm
<br> and ran echo "some random text" > /dev/ttyS0 in another xterm and the text appeared as expected in the 1st xterm.<br> - I ran the check for update routine after doing a reset on my H20 receiver to pull down the latest firmware.
<br clear="all"><br>I'd love to have any input from other H20 users. Maybe I'm missing something. My next attempt will be to go write a shell script to run through every possible combination of parameters to the
directv.pl
script. I'm using the 1.7 version, which I believe is the latest, contrary to what's reported on that wiki page cited above.<br><br><br>
