You would be the first person that I know of who uses HylaFAX with an LT
Winmodem.  LT Winmodems are software modems, not hardware, so I don't know
that there is such a thing as "hardware flow control" for a winmodem.

You're likely going to have frequent communictations problems with other
fax machines out there... but who knows? you're the first here, I think.

Nah, you want to use Class 1.  HylaFAX code for Class 1 is better than
Class 2/2.0, anyway.  If you dig through the archives, you'll see lots of
discussion on Class 1 vs. Class 2, and I think that the general consensus
is that most people will be better off in Class 1.  Such has been my
experience.

The only other recommendation that I could give you would be to use CVS
version rather than the simple 4.1beta2 tarball.  That is, unless you're
using SCO or HP-UX... or OpenBSD (from the last reports).  See
http://www.hylafax.org/cvs.html
