Where in the kernel is 33.6 enhanced support? Basic Rockwell support for it seems to be missing.
Cheers, Dean McEwan. Currently hacking KGI, which I don't understand, oh and ask me about OpenModemTalk...

Let me guess - do you have a so called 'winmodem'? Then perhaps you should
read this:
http://www.linmodems.org/
http://www.iac.es/galeria/eddie/linux/modem/winmodem.html
Otherwise, if your modem claims to support v34 then it should be able to
do this by itself. IMHO, the kernel's most important task is to make
serial ports available to communication programs, not to implement
protocols (especially when manufacturers won't give specifications to
people wanting to port them to Linux).
You can also try this:

I'm not sure if this is the answer to your question.

No, I think I know the difference, the kernel IS supposed to support hardware modems, as for winmodems, ive written a HSP to help port them, which if anybody wants, mail me, i'll set up a sourceforge site for it soon.
Cheers, Dean.

Well, you are right - the kernel support for winmodem is good if one wants
to use ppp et al. On the other hand, it seems that having support for some
specialised protocol can produce a lot of overhead in some cases. For
example, I once owned very simple Zoltrix, that could do error correction
and compression only via the software driver (available only for windows,
of course). So, it was almost unusable until I started doing ppp on it.
The ppp driver took care about errors and compression - now, with the same
futures implemented in lower layers it would be a waste of cpu.
So, if you want to do kernel support for winmodem, it would be probably
good to remember about ppp. Of course, if you choose to implement full
support and emulate v34 or anything else, you would be able to turn the
compression (and || or) error correction off either on the emulated
'modem' or in ppp options.
Anyway, I think you could have a look at http://www.linmodems.org. It seems to
contain some interesting things.

Actually only hardware Rockwell support is any good...
Cheers, Dean.
