The ATI Mach (8/32/64) cards emulate an old IBM 8514 style video adapter which has some of its I/O ports at the same location as the standard for COM4 on IBM compatible PCs. (Don't remember the port location off the top of my head). To use the ATI card, you would have to disable or move the COM4 serial port. No other work-around exists. Then again, this may not be your problem. ================================================================== Bob Greenwald President, Software Design Consultants, Inc.
