That should be about right, there are various differences in systems but
generally that should work for linux.

Ok, iaxmodem probably needs root to unlink and symlink the /dev/ttyIAX
file, given /dev settings.  Or at least be suid until after it has done
this.

asterisk doesnt access the device itself.  Does /dev/pts/1 actually
exist?  It should, but lets just cover the bases :)  

Note that /dev/pts/1 is dynamically assigned, it may change, especially
if you have others log into that system on a pseudo tty (ie not console,
xterms take a pseudo terminal as do ssh logins).  It should however, on
your system anyway, be /dev/pts/XX  where XX is some integer.


The fact that its /dev/pts/1 makes me think that something is
on /dev/pts/0 already, which means that kernel support for it should be
there, unless by some amazing coincidence it was limited to 1 (default
is 256 iirc).  So I really dont think that is the problem.
