 I am using the following configuration:
 
 --garmin=serial,in,1,COM1,9600
 
 I have also attempted to interface FG with another computer that was also
 running FG that was configured as follows:
 
 --garmin=serial,out,1,COM1,9600
 
 However, I have the same problem.  After the first line of data is read, FG
 (on the receiving end) crashes.
 
 Any ideas?

I haven't tried this in a *long* time (and probably never with a real
gps.)  Can you compile the garmin.cxx code with the -g option and run
this in gdb and see what the back trace says?  If we can pin point
where it is crashing it probably won't be too hard to figure out why.

 Has anyone had any success interfacing FG with a GPS?  I have been
 attempting to interface FG with my garmin handheld. However, after reading
 the first line of serial data, FG crashes.  The first line of data is read
 and parsed correctly but FG crashes before the second line of data is read.

I suggest you look at the line terminations being sent by the GPS ?
