Hi Hans.
I think the difficulty will be whether it was written for the DJGPP[1]
compiler (a port of GCC to DOS, as I recall) and this uses C library
calls and the actual ncurses library. If it was written using classic
DOS interrupts and direct video hardware access, then the task would be
quite a bit more difficult, I would think (note that I am guessing, not
having done anything like this).
Perhaps the easiest way is to install FreeDOS[2] in a virtual machine
(QEMU[3] is in the archives, Virtualbox[4] requires a slight bit more work)
and run the program from there. Then tackle development in that
environment while slowly working toward a native Linux build.

As a radio amateur myself, I find the above intriguing. I don't recall
hearing of this program before. I am aware that such radio transmitter
fingerprinting has been known for a long time.

Better would be to send the URL. What CMS is it in, CVS, SVN, something
else? I'd be interested in preserving the source code history as much
as possible and then moving that into Git.
