I have bought an old GW212 card for my PC/XT. This card has battery-powered RTC, COM/LPT controller, game port and FDD with 1.44MB 3.5" support (its own BIOS).
My XT has LPT1 and COM1 onboard. So, I need to switch card to LPT2 , COM2/3.
But how to do it? Which jumpers I need to change?
Drawing below shows my card (sorry for quality - I lost my camera).


This red rectangle with black dot is a jumper group - 9 jumpers, 2 pins each. Below board layout, there is a drawing of this block (LPT1, COM1/2 set???).

Which jumpers are responsible for COM/LPT ports? There is no answer in TH99!
