[Xastir] USB on Linux for TNC

[Brian Heaton]

Rich,


	Its the exectute only permission for everyone on ttyUSB0 that concerns
me the most.  Does anyone know any reason why execute permission are
needed on a USB serial port??? 

	Baesd on what's in the INSTALL file the solution that looks best to me
is changing the xastir binary's group to the same as the port (uucp) and
then make xastir setgid uucp.  That should fix it up pretty well. I'm
not sure which of the possible solution you chose based on your earlier
emails.
