Whenever I try to activate a serial tnc connection it causes my Xastir

I have checked that all of the configuration is correct duch as
/dev/tty.usbserialFTDI845 for the serial port and I have use a terminal
program to talk to the tnc and everything runs fine there.
Any suggestions?
Who is the group owner of that device? Have you added yourself to that group
and logged out/in again to gain the new group?
Are the group permissions set properly on that port so that both the owner and
the group can read/write the port?
If all else fails, have you tried setting Xastir SUID root to see if that overcomes the
issues? (As root: "chmod 4755 /usr/local/bin/xastir")
On this OpenSuSE system the ports look like this:
$ cd /dev
$ ls -al | grep ttyS
crw-rw---- 1 root dialout 4, 64 Apr 8 09:11 ttyS0
crw-rw---- 1 root dialout 4, 65 Apr 8 09:11 ttyS1
crw-rw---- 1 root dialout 4, 66 Apr 8 09:11 ttyS2
crw-rw---- 1 root dialout 4, 67 Apr 8 09:11 ttyS3
crw-rw---- 1 root dialout 4, 68 Apr 8 09:11 ttyS4
crw-rw---- 1 root dialout 4, 69 Apr 8 09:11 ttyS5
crw-rw---- 1 root dialout 4, 70 Apr 8 09:11 ttyS6
crw-rw---- 1 root dialout 4, 71 Apr 8 09:11 ttyS7
So I would add my user to the "dialout" group and log out/in again to be able to use the ports. Both the
owner "root" and the group "dialout" for these ports are marked "rw".
The serial port names I'd specify in Xastir would be "/dev/ttyS0" or
"/dev/ttyS1". I'm not using USB->Serial adapters at work or at home to talk to TNC's. I
found them problematic at home so went to real serial port cards. Some of course don't have that
option.
