Yes, you _can_ set it up that way, and I have it running that way at
home right now.  One of the Xastir Solaris users is running it that
way too, because of course Solaris doesn't have AX.25 in the kernel.
Only one program at a time can talk to it.

The other way to run soundmodem is as an AX.25 networking device.
If you do that, then programs that can talk to that type of
interface can all share the interface at once.  Very much like an
ethernet interface in that case.

Xastir will talk to either type (you knew I'd sneak that in there
somewhere, didn't you?).
