    COM 1/2/3/4 working on 865 Chipset


      This is an embedded application, hardware manufactured by Intel's Embedded Channel Partner!


      In a DOS application, onboard serial ports (COM 1/2/3/4) work fine on 875P chipset but not on 865 Chipset and beyond!


      For chipsets Intel 865 and beyond only COM 1 & COM 2 work fine, while COM 3 and COM 4 show no response!


      Is there any functional difference in the two chipsets which can affect COM 3/4 not to work on 865 Chipset?
