HdwP442216550 Card Configuration
The four port card has two modes of operation. These modes are named Compatible
Mode and Enhanced Mode.
In Compatible Mode the first two ports on the multiport card are
fixed to the address of COM1 and COM2 respectively (Address 3f8, IRQ 4 and Address 2f8,
IRQ 3 respectively). The other two ports share a third IRQ with the base address and IRQ
selected by the switch block on the board.
In Enhanced Mode all ports share the same IRQ. The base address
and IRQ is selected by the switch block on the board.
WCSC develops and sells all the necessary libraries and DLLs to
support this multiport card under the above mentioned operating systems. Contact WCSC at
+1 (800) 966-4832 or +1 (281) 498-4832 for additional information, or visit our web site
at http://www.wcscnet.com.
Refer to the figures for location of switches/jumpers.

Compatible Mode
In compatible mode, the address and IRQ of the first two ports are
fixed. The first ports address is the standard COM1 (address 3f8, IRQ4). The second
ports address is the standard COM2 (address 2f8, IRQ3). Ports three and four
addresses are determined by SW1-2. Ports three and four IRQ is determined by JP4,
SW1-3, SW1-4, and SW1-5.
