Help wanted... don't know the meaning of the DIP switches and Jumper of an 8-Bit ISA card labeled Acer PB85026-2L (which is also selled at Ebay as "Multitech").
See picture, my PC/XT only recognizes the parallel port, but not the two serial interfaces :-(

Any hints related to/about the DIP switches and jumper?

A bit disappointed about no response, I started to try Switch SW1 1of8 and 3of8 and set them to ON (there were set to OFF).
Luckily exactly these two mini dip switch positions (1 and 3) are responsible for activating both serial interfaces.
