Probably not - but surely isn't is a well-accepted method that software is 
often used to fix bad hardware design?

I firmly believe that half the reason so many companies refuse to open-source 
their drivers is because it would horrify us all at the number of "special 
case" if {} blocks and /* fix for lack of blablabla support */ comments that 
we'd find :)

From what I read, isn't the polarity switch fairly redundant? Would it not be 
enough to just leave the fskmodem.c code running all the time (for a single 
X100P on a 1GHz system, I can't believe this will have a noticable CPU hit), 
instead of the current 'wait for a ring, then listen for CLID' ?

I have tried to look into the source, but I'm no C coder and just ended up 
getting increasingly confused :(

Indeed, would there really be much extra work required, since the UK FSK 
databurst is in the same format as the USA (from what I understand) - so much 
less work would be required to suport this, than the DTMF-based CLID...

Cheers,
Gavin.
