Thanks-
Tried that- set it to the /dev/ttyUSB2 that I am able to use the command line to send messages to the receiver.
In the web admin pages, when I try to figure out which commands are right for my device, the command is send to either the core (Device #1) or the core/hybrid (my device #20). Is this correct? Is the command supposed to be send to the device that the receiver is connected or is the command supposed to be sent to the receiver itself by way of the port on the MD/Core. My receiver is device #136, shouldn't the command be sent there?
I'm getting a usb->serial that has the PL2303 driver that this forum:
http://forum.linuxmce.org/index.php?topic=8226.0 confirms works.
When I get that working, I will get back to this other cable...
Thanks for you help
