Huh? What instructions? I never wrote anything about making serial 
ports modular or trying to control a cable box...

Your serial port should just work, if it is enabled in the BIOS...

Looks like it.

No, the PVR-250 remote interface is an i2c bus, not serial. In this 
case, /dev/lirc is simply a character device. Run 'ls -l /dev/lirc' to 
see what you have.

It isn't. It is /dev/ttyS1 (which is typically the character device 
file for COM2; COM1 should be /dev/ttyS0, which could be part of your 
problem). It is possible that for some reason, you have /dev/lirc as a 
symbolic link to it, but you shouldn't. If your PVR-250 remote is 
working, then /dev/lirc should a character device, as I said above.

I have no experience using the PVR-250 remote and controlling a cable 
box at the same time (or controlling a cable box at any time), so I 
can't be of much more help at this point...
