[Xastir] Serial port issues with Xastir on OS X

[Matt Kassawara]

I've tried configuring the interface as "Serial TNC" and "Serial KISS 
TNC" using the dynamic device created by the USB-RS232 adapter driver... 
typically /dev/tty.PL2302-######## where the driver generates ######## 
based on device number.

Further investigating this issue, I ran Xastir via Dtruss (similar to 
strace on Linux) and noticed it attempts to use the /var/lock directory 
for a serial port lock file which does not exist on OSX.  I found the 
directory hard-coded in interface.c.  Changing it to the something more 
appropriate for OSX did not fix the problem.  Unfortunately, Dtruss 
doesn't seem to provide much output beyond an attempt to read/write a 
lock file in the /var/lock directory before Xastir hangs.  Perhaps 
interface.c contains other Linux-specific items which break on OSX?
