Yes.  See: http://www.hylafax.org/cvs.html

Let me add a word of caution, however... CVS is a development branch.  
Hopefully you find no problems, but you just may so don't count on it 
for uninterruptible production support until you've thoroughly tested 
it.

It's all been checked-in now... plus some.

The CVS version offers extended resolution support for Class 2 modems 
that support it (like the MT5634s).  Other than that HylaFAX 4.1.6 
already supports all of the MT5634's features with the exception of 
color faxing (which HylaFAX doesn't support at all).

It depends on what you're faxing goals are.  ECM is a must if you want 
perfect document delivery... or even legible document delivery on very 
noisy lines.

ITU T.30, T.31, T.32, T.4, and T.6 are adequate reading ;-)

The ITU should give you 3 for free per year.
