Open a terminal program, short pins 2 and 3, and see if you see what
you type.  Simple loopback test to verify communications out to the
DB9.

Option 1: xastir.  OS X is unix.

Option 2: virtual machine (virtual box is free, Parallels or VMware
are $) running either linux (xastir, only easer to build than on OS X)
or windows (running whatever APRS app there is for windows).
