      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.

I assume that the problem is in XASTIR , and generating the flow control (handshaking) signals.   When I run the program " GTKTerm ",  the port opens and runs as a packet terminal .(9600,N,8,1  flow control none).

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.
