The Laser pinouts would require a Laser manual (which I do not have).
The first two are available in any good reference. For example I have a catalog
from CommsWare and in the data section at the back we find:

The following is archived in /pub/apple2/hardware on
apple2.archive.umich.edu: (The original info was stolen off the net)
-=-=-=
Name: Apple SSC
Type: Super Serial Card
Short description:
The SSC gives the Apple ][ a serial port (RS232). Up to
19200 baud are possible. Full handshake is supported.
Installation:
The card plugs into Slot 1, 2 or 3 of the Apple. Slot 1 is
usually for a serial printer (Imagewriter), Slot 2 for a
modem and Slot 3 for a terminal.
The DB25 connector goes to the printer/modem/terminal line,
the 10-pin connector on the other side of the cable goes
into the cable socket at the rear side of the card.
Jumper settings:
The card has two jumpers and a additional jumper block.
The jumper block can be installed two ways:
1) Arrow pointing towards the word TERMINAL
2) Arrow pointing towards the word MODEM
Jumpered as MODEM, it will wire thru, jumpered as TERMINAL,
it will twist 2-3, 4-5 and 6-20 (called null modem).
The jumper switches are called SW1 and SW2, the switches
are numbered SW1-1 to SW1-7 and SW2-1 to SW2-7 from left
to right.
SW1-1 SW1-2 SW1-3 SW1-4
