I did find a fix, it is not mine but I can confirm that it does work:

Terminal parameters were not correctly setup in COM_open().
Following patch fixes this. Please consider to apply this patch in
your branch for next distributions.

The interestring thing is that a message from Apr 17, 2008 says the
patch has been applied but when I download the source from sf.net the
ow_com.c file does not seem to contain the patch? Once I edit ow_com.c
and made the changes my LINK started working

You know guys I have been monitoring the mailing list for years,
ever
since owfs was in its infancy but lately I see no post
addressing few
bugs that simply make the source unusable.
I discovered this just recently when I got the latest svn (I
have been
running an older version for 3 years) - there was a DTR line fix
which
makes serial LINK modules not work since they don't get their
power
Has this been fixed? Is it just me NOT using USB adaptors any
more hence
no one had complained about that?
Thanks
