I chased this down by looking at the pin outs on the ISA bus, Lots of documentation on the WEB try this as a start http://www.gw.total-web.net/~dperr/pc_io.txt and http://www.gw.total-web.net/~dperr/pc_hdwe.htm If you old ISA card is so configurable I would try an UART chip for it as it is much easier to put a chip into a sockect than cutting and soldering tracks on a circuit board. Note with this quick fix you can only have a MAX of 4 serial ports. You could in theory change the address of the I/O ports but you would have to make sure your new I/O port range did not conflict and that the software is able to work with these non-standard port address.
