[Xastir] Xastir on Ubuntu locks up opening serial TTY

[Neill Thornton]

All,



Hoping for some guidance here.  I have been running Xastir on an Ubuntu box just fine for several weeks.  Today I upgraded to 14.04 and noticed Xastir was locking up when started, not even displaying a map, just a blank grey screen.



I went in to .xastir/config/xastir.cnf and disabled the serial port to the TNC by setting DEVICE0_ONSTARTUP to 0.  Now, when I start Xastir I get the map, and connect to the APRS internet network no problem.  If I try to manually start the TNC interface, it locks up as soon as I hit "Start".



If I run xastir -v 2048, I can see the verbose logging going by... and when I try to start the TNC interface the log halts at "Changing euid to 0 and egid to 1000".



I can access the serial port (/dev/ttyS5) just fine using cutecom and minicom without root privs, and see TNC traffic.



Xastir has been chmod 4755 to see if that might fix it, it doesn't.  Running xastir as root doesn't fix it either.



I downloaded the latest source tree via CVS and compiled that, and it still doesn't work.



Does anyone have any ideas here?  Some googling really did not turn up much.



Thanks,



Neill
