Card configuration
The PCL-841 has two ports, each with one jumper. The jumpers set the
IRQ for the ports, which can be configured separately. A DIP switch
sets the memory base address for each port. The following chart
shows the function of the jumper and the switch (see the previous
page for jumper and switch locations).

Default settings
Port I is set for COMI (IRQ=12, Memory address=DA00:0000).
Port 2 is set for COM2 (IRQ=IS, Memory address=DA00:0200). ;
If you need to change these settings, see the following sections.
Otherwise, you can simply install the card. Note that you will need to
disable your CPU card’s on-board COM ports, if any, or set them to
alternate addresses/IRQs.
