There's more to this form of setup than what you did.  Look up the
Linux AX.25 HOWTO document.

Yes, an alternate method but it doesn't use the kernel AX.25 drivers
in this case.  No matter if all you want is to connect Xastir to it.

The missing piece here is to grant read/write privileges to the
serial port, for the user or group that Xastir is running under.
Alternately you can do "chmod 7455 /usr/local/bin/xastir" as root,
which lets Xastir run as root when it needs to.  Xastir backs off to
normal user privileges when it doesn't.
