I feel here that I must say that the "port" wasn't from the Python version, but from the port Rob Hamerling did to OS/2, and it was already written in C. My task was to add conditionaly compiled code for the Windows API specific parts. Mainly low level serial port handling. 95% of the code is still Robs original C code. And half of my time was spent reading "msdn.microsoft.com"... :-) > That s great news! I had also thought that, if someone else had done it :-) :-) Well actualy, I *do* think that also. And about a GUI. Anoter way would be to write it as a "system tray" task. So you could point on the Wisp-icon in the "tray", right click and select "Go" from the pull-up-menu. Or "Select File", "Select Port" or whatever. But the command line version/interface will of course still be there. And, at last, *this* port was to support a specific project, I've no idea what will happen in the future...
