Oddly I found information on how to do that very easy to find for
Unix. Conversely wanted to do the same thing in Windows and hit a
brick wall. Everyone does it differently with different compilers. So
I told the boss a Windows Weenie would have to take over.
Had a perfectly good minimal text-only program which formed serial
Modbus ASCII packets, and displayed the response, under FreeBSD.
Would be interested in a library for mingw or similar with termios
cloned. Else some simple documented way to do unbuffered serial I/O.
ASCII Modbus doesn't really require unbuffered I/O but thats the path
I started on and would be required for Modbus RTU mode.
