persistent ptys

Hi,
It seems BSD style ptys are on the way out, and most systems will soon
have just Unix98 style ptys. This makes me want to move something to
Unix98 ptys, but I'm not sure of the appropriate way. The issue is that
things like HylaFAX expect to work with well known, persistent, names
for modem ports. A 100% soft modem in user space can easily provide that
with BSD ptys. With Unix98 ptys it is not so obvious what to do. Most
commercial soft modems don't have this issue, as they are part kernel
space/part user space designs. Obviously creating a link to a
dynamically generated pty with a well known name, and various other
things could be done. However, I assume other people have had to do
similar persistent pty things, and there is a well defined common
practice for it. Can anyone tell me what it is? :-\
Regards,
Steve
