I have a digitizer. Several years ago, a colleague of mine wrote QuickBasic code to make it useful (ie digitize stuff). It is used to working on a DOS w/o Windows machine. Iím trying to get it to work on a Windows machine. I download and installed the Windows drivers. They obviously work because now in just a regular Windows environment I can use the digitizer pointer or normal mouse interchangeably. But the QuickBasic program doesnít correctly interface with the digitizer. The digitizer is connected to the serial port. I think the QB program recognizes the presence of the digitizer, but canít interrupt the info to and from it. Any ideas? Would writing a piece of Visual Basic code to interface with the digitizer and the QB code be possible? How come the QB program canít figure out whatís going on? Any thoughts on the subject would be very much appreciated.
