[Xastir] {Disarmed} Xastir Freezes

[Mike Swiatkowski, AA9VI]

Well, I managed to get the interface 0 hard fail to go away but I cannot prevent Xastir from freezing every time I open up the serial port with the Peet Ultimeter 2100 weather station on it.  I tried USB to serial interfaces and PCI to serial interfaces and I get the same result.  The Debian 6 box is fully talking to the TNC but why not the WX station serial port?  Why would it freeze Xastir?  

Then I went as far as blowing away the entire OS, reinstalling, adding my user to the dialout and sudo groups and reinstalling Xastir.  I did the chmod 4755 to /usr/local/bin/xastir

Again, the program freezes as soon as I open the serial port.  I can only get Xastir to relaunch once I clear out the xastir.cnf file.  As soon as I try an open the port with the weather station on it, Xastir freezes.  Again, I can see the data from the serial port easily with minicom.  Xastir is just choking on it.  

any ideas?  Day 7 without APRS now.

I have a vague memory of Debian Squeeze being stubborn about serial
port permissions as long as the user was not a member of the group
'dialout'.  As root, issue the following command to add your username
to the group, dialout.

  usermod -G dialout username

where 'username' is the username that starts Xastir.

You can see what group(s) of which your username is a member by
issuing the command below (not as root)

  id -a

The above will verify if your user is a member of 'dialout' or not.

The fact that your other methods didn't work is puzzling, though - I
know I have been able to take the insecure way out for something quick
and dirty and change the permissions of /dev/ttyX0 to '777' and see
things work.

Hope this helps.
