     These settings are listed and described in the newsgroup FAQs on sites
like Ground (pure text), USA2WUG (formatted text), and II Computing (html).
Here is a snip:

013- What are the settings for the Apple Super Serial Card?

     Here is some information about Super Serial Card (SSC) Settings:


Recomended Slots

  Slot 1 for terminal use (e.g. printer)
  Slot 2 for communication use (e.g. modem)


Jumper Block- configures serial I/O lines. This does not set the 
  operating mode of the card. Operating mode is set via the 
  DIP switches.

  For typical "terminal" (printer) use, label is right side up (arrow
  points DOWN), DIPs are set for "terminal" operation, and a printer
  cable connects to the printer.
  This jumper setting can also be used with a modem cable to make a 
  NULL modem connection to another computer. (DIPs would then be set 
  for "communication" operation.)
   
  For typical "communication" (modem) use, label is upside down (arrow 
  points UP), DIPs are set for "communication" mode and a modem cable
  connects to the modem. To make a NULL modem connection to another 
  computer, use a modem cable + NULL modem adaptor.
      

Note that RS-232-C signals on the SSC use negative-true logic;
that is, they are true at 0v and false at +5 volts.

SW1 Dip Switch 5-7 Settings

                                      SW1-5  SW1-6  SW1-7

"Communication" (modem) operation     on     on     on
"Terminal" (printer) operation        off    on     on*


Note

Switch SW1-5 and SW1-6 help define the operation mode of the card.

1-5   1-6   Operation Mode
on    on    Communications
off   on    Printer
on    off   Emulate Apple Serial Interface Card with P8 PROM
off   off   Emulate Apple Serial Interface Card with P8A PROM


Switches SW1-7 and SW2-7 select between the standard and secondary
Clear To Send signals when the jumper block is set for "terminal"
(printer) operation.

1-7   2-7   pin
on    off   CTS
off   on    SCTS

If the jumper block is set "Communication" (modem) operation,
SW1-7 should always be ON and
SW2-7 should always be OFF.

*For "Terminal" (printer) operation, the setting may vary.
If using an Imagewriter II
SW1-7 should be ON and
SW2-7 should be OFF.



SW2 Dip Switch Settings

Switches SW2-1 through SW2-4 functions depend upon whether "Terminal"
(printer) or "Communications" (modem) operation is enabled.

correct settings for SW2-5 (on= auto-send linefeed after CR) and
SW-6 (on= enable interrupts) may vary.
