Curt WE7U--
Curt, Thanks for the help. My problem was the lack of a capitol
letter. The /dev/lttyS0 works great. Thanks for the help !

Lee, Many thanks for your suggestion. I Will update (later) to XASTIR
V2.01. I now have the old version working. When I get my feet down, I will
follow your suggestion.

Are you trying to open "/dev/ttys0" or "/dev/ttyS0"? On Linux the latter is
what you would refer to as "COM1" on DOS/Windows. "COM2" would be
"/dev/ttyS1". Note the capital 'S'. Linux is case-sensitive, whereas DOS and
Windows (at least up until recently) were not.
Other issues you may be having are ownership or permissions of the port.
GTXTerm may be set up to assume root privileges while opening the port (so it
can get around these restrictions), whereas your Xastir install may not be.
This is a little tricky to explain, but here's how I would start:
*) Run "ls -l /dev | grep ttyS" from an Xterm window. You should see something
like this:
> ls -l /dev | grep ttyS
crw-rw---- 1 root dialout 4, 64 2010-09-09 09:38 ttyS0
crw-rw---- 1 root dialout 4, 65 2010-09-09 09:38 ttyS1
crw-rw---- 1 root dialout 4, 66 2010-09-09 09:38 ttyS2
crw-rw---- 1 root dialout 4, 67 2010-09-09 09:38 ttyS3
crw-rw---- 1 root dialout 4, 68 2010-09-09 09:38 ttyS4
crw-rw---- 1 root dialout 4, 69 2010-09-09 09:38 ttyS5
crw-rw---- 1 root dialout 4, 70 2010-09-09 09:38 ttyS6
crw-rw---- 1 root dialout 4, 71 2010-09-09 09:38 ttyS7
The "root" is the OWNER of the port, while "dialout" is the GROUP. You may see
something different on Ubuntu, but in any case you want to know what the GROUP
is.
*) Add that group to your user account, using whatever tool Ubuntu uses for
this. After you log out and back in again (you don't need to reboot your
machine), your user when then be a member of the group.
*) Make sure that the above shows "cwr-rw" for the port of interest if you
expect to be able to open the port using the above GROUP method. If it doesn't
then there are additional permissions for the port that need to be set up, and
this can get tricky if the ports are created dynamically on boot.
Yet another thing I should mention: Xastir-1.9.4 is VERY old. Consider
upgrading to 2.0.0. http://www.xastir.org has Wiki pages specific to Ubuntu
that should help you with this. Look under the "Installation Notes" heading,
then find your specific version of Ubuntu.
Lastly: If any of the above is unclear, or you get hung up on any part of the
process, please ask again right here on this list. I went ahead and approved
your posting 'cuz I saw that you tried to subscribe today, but perhaps you sent
the query before you subscribed or you subscribed a different address than you
appeared to post from. In any case we need to get your posting address
straightened out too so it's easy for you to ask questions here.
