[Xastir] Xastir and serial port issues

[Jim Tolbert]

Hey, Craig........  What a Guy!  Thanks.... after running the echo 
command -- at 9600 baud 8,N,1 I get the Kantronics header in Minicom.  I 
still don't get anything in Xastir, but then I don't have a radio 
attached yet <long story>.

What I am taking away, is My Serial Port Is Functional.

I am assuming that Minicom sets the serial port parameters and leaves 
them set.  Does that seem reasonable?  Is there a way to check as to 
what they are set to?  Should I be running Xastir with Minicom running 
or not?

Many thanx............. jt
