I'm curious how one would set up multiple digital cable connections on a single backend - even just two would probably be ok. Being only familiar with the PVRx50 products I envision you'd set it up like this.
Cablebox - serial interface - recording device
Digital 1 - serial 1 - pvr150(1)
Digital 2 - serial 2 - pvr150(2)

Is this particularly difficult to configure?

I would think you would have to change the channel change script to reflect sending a signal to dev/ttyS1

The script most people currently use is dct-channel and the default port is ttyS0 (COM1)


I would think if you edited this section of the file channel.c to reflect dev/ttyS1 (COM2) that might work for your second serial port.


Of course you'd have to compile it then and probably name it something else (to prevent overwriting the script for ttyS0) and then point to the new file in the external channel change command of mythtv-setup.

At least that's the way I would try to do it. (untalented linux noob here)

Anyway, I'm really curious as to whether you'll be able to get it working at all in R5D1 on ttyS0. I seem to be having a bitch of a time with it. Seems like the serial port is blocked somehow but I can't nail down the reason.

Appreciate any feedback on how this works out for you
