[mythtv-users] controlling two digital cable boxes

Peter, you may have to hack the source of the C program if you're using
that.. It scans the serial ports automatically.. If you're using the perl /
python / whatever code, you should be able to edit each instance to point to
the right port. Just a FYI for when you go to set up the second cable / box.

Thanks all for the advice.  I have a USB->Serial converter (Belkin) lying
around and so I tried for a while last night to get that working, but with
no luck.  It might actually be working (the LEDs on the device light up in a
semi-convincing manner), but I am not able to get the channel script to talk
to it.

So, I'll go ahead and get a PCI serial card.  As has been pointed out, they
seem cheap and well-supported under linux.  Furthermore, this will give me
two additional serial ports in case I want to add a third cable/satellite
box at some point...
