I have a Rover 346 running with RT480 postprocessor. I run it with a software called PanelCAM. It works fantastic on Windows XP and let me format the floppy with its the special formatting for machines running with RT480. But my Rover has a serial port and I would like to use it. As far as I understand, I need a software called RTCOM, probably from CNI but I am not sure no information about that on their website). But I have also heard that the protection dongle has been modified to make it run on XP. Has anybody some information about this ? How could I buy the version of RTCOM to make it run on XP ?
