    What specific driver affects the RS-232 serial port on a C204 chipset and how is it identified in hardware manager?


      I have a S1200BTLR motherboard. It has two native RS-232 ports that are integrated into the C204 chipset. The device I talk to over the RS-232 port has intermittent communications. If I install a USB to RS-232 converter, it works just fine. I need to know how to identify the specific driver that would have any impact on the performance of the serial port, and how to see all that in device manager. The only thing you can do in BIOS is to enable/disable the port...
