I have not tried the FreeBSD ltmdm port, so I cannot provide anything 
further about its performance than fbsd_user has.  External serial modems, 
even inexpensive ones, do work very nicely with FreeBSD.  However, if 
purchasing a new modem does not seem reasonable to you, then you may wish 
to try installing FreeBSD and the ltmdm port, and see what you think.  
After all, your experience with FreeBSD and the ltmdm port, not anyone 
else's, is what really matters.
