Check the ownership and permissions for the USB port you're trying to
use. It should be something like "/dev/USB0" or "/dev/USB1".
ls -l /dev/USB*
See what group the USB ports belong to as it it might be something other
than dialout. The permissions for the group need to be read/write as
well so it should be something like:
crw-rw---- 1 root dialout
Also make absolutely sure that the user you're logging in as is a member
of the "dialout" group, or whatever group is listed for that port.
grep <user> /etc/group
and that you've logged out and back in since adding that user to the group.

Curt,
Actually, the device is /dev/ttyUSB0 and it does have the root DIALOUT
user/group values. And, they both are 'rw'. The only thing I can think
of is that I may have done the xastir-cvs-thinky incorrectly. Also, as
I pointed out, on my TC-1100, user 'dale' is not a member of the group
DIALOUT, but xastir still works on that machine under the 'dale' user.
Also, logging out and back in did not solve the issue.
Why would GtkTerm have no problems? What's so special about that
program, that xastir doesn't have? Very strange.
Still mystified... 73 - Dale. KG5LT
