According to my own implementation experience, all you get for 8 Pentium
MHz is Bell 10x, i.e. 1200 bauds or maybe even 2400 bauds. I doubt
you'll want this :-)
NB1: for the code (which includes cycle counter measurement code) see
drivers/net/hamradio/soundmodem/*
NB2: If you design kernel space API well enough (which isn't
unfortunately
true for OSS) then almost all of the processing is a user space issue.
Also, you most likely will need floating point, as floating point is
much
faster than integer on some expecially intel processor models.
NB3: If it's so important for you to get winmodem support, make the docs
easily available, such as the ITU V series for a start. I'd likely be
willing
to contribute to such a project, but I'm too lazy to bother trying to
get these standards documents.
