Fred,
As I read it, the <exec> script </exec> macro pair is primarily for
Linux versions. I think you may want to experiment with it and see if
you can get a script from linux to work. In the linux version, it is
used to start a perl script located in the .fldigi/scripts directory.
The windows equivalent would be to create a directory named "scripts"
under the fldigi.files directory. Maybe try a windows perl version or
something that will work with cygwin? This could get very complicated.
