[mythtv-users] Control DirecTV D11 via serial port

Just curious if anyone else has gotten this to work and any advice  
they could lend. I'm attempting this with a USB to Serial adaptor and  
a null modem connected to my mythtv box. I installed the perl module  
Devices:SerialPort and the modified script linked from http:// 
www.mythtv.org/wiki/index.php/Controlling_DirectTV_D11_via_USB.  
Unfortunately all I seem to get is:

[mythtv at mythtv ~]$ d11control.pl verbose 2

Error excessive retries
         (in cleanup) Can't call method "opened" on an undefined  
value at /usr/lib64/perl5/site_perl/5.8.6/x86_64-linux-thread-multi/ 
Device/SerialPort.pm line 2020 during global destruction.

I tried changing baud rate from 115200 to 9600 with the same results.  
I'm sure my serial port is ttyS0 since I've only got one and recently  
had an ir blaster working on it without a problem (aside from missing  
channel changes about 50% of the time which is why I'm trying this  
route).

Thanks,

Brad
