The RS-232 library is now available in the SF Package Manager for subscribers.

I currently have a library with a Fortran wrapper now working, and I'll see that the source code is available in the next few days. The Fortran code is actually wrapping the RS-232 library in a module that should be easy enough to use.

I would also like to know if com port communications are possible using Approximatix Fortran!
Anyone have any experience doing this?

I'm not sure modern Windows machine still implement "magic" files like COM1 such that a call like OPEN(FILE='COM1', ...) would work without substantial additions to the Fortran runtime library. You would be better off using an external library. However, I don't know of a Fortran library, so I would guess one would have to wrap a C library to access the COM port. I'll look around, but I can't make any promises.

Can anyone suggest a way for Simply Fortran to support serial communication through a COM port?

With modern computers a COM port is usually implemented as a USB-UART (RS-232) converter which shows up in the Windows Device Manager as a COMn port, n being the number assigned to the port.

What I need is to be able to Send/Receive data to the COM port from within a Fortran program

What would be the simplest way to do this?
