same mode, or you can configure each Tx and Rx on one port to
operate in different modes.

The base address of each port is selectable by a 6 position DIP
switch, SW1 for CH1 and SW2 for CH2. Refer to page 9 for the
locations of the DIP switches SW1 and SW2. The base address can
be set anywhere in the I/O address area from hex 200 to hex 3F8. If
you have more than one card installed you must select different base
addresses for your card. Factory default settings for base addresses
are Hex 3F8 (COMl,SW1) and Hex 2F8 (COM2,SW2).
