Okay. I re-read what you wrote, and I think it was just a bit 
ambiguous, and I misinterpreted it on this part.

Hm... I have no serial stuff, so I can't provide much input there, but 
I do know the character device is what works for the PVR-250's onboard 
remote interface. Actually, I just had a thought... I believe there are 
serial remote interfaces that don't use the lirc_serial kernel module, 
and simply use a symlink to a serial port for /dev/lirc. I believe the 
character device is probably standard for any lirc interface that uses 
a kernel module. Then again, I may just be talking out of my ass... I 
didn't sleep much last night due to a sick child... :)
