In 2.0+ releases of Interactive Unix, the driver was updated so that
the second switch (the middle one on the board) needs to set thusly:


  on                 x       x   x       x

  off        x   x       x           x

  switch     1   2   3   4   5   6   7   8


which amounts to setting the I/O address to 348 for the
first ICC card. Here are second switch (I/O address settings)
for second, third, and fourth cards:


(2nd card: I/O address: 34C)

  on                 x       x   x

  off        x   x       x           x   x

  switch     1   2   3   4   5   6   7   8



(3rd card: I/O address: 350)

  on                 x       x       x   x

  off        x   x       x       x

  switch     1   2   3   4   5   6   7   8



(4th card: I/O address: 354)

  on                 x       x      x

  off        x   x       x       x       x

  switch     1   2   3   4   5   6   7   8


How you know that switches are set correctly: after
switches 1 and 3 are set to default and switch 2 is
set as above, put ICC driver in kernel, build kernel,
shutdown to install. Put card in box and reboot.

If everything is everything you will see the following
just before the console login prompt:

 ICC card 0 installed
 Notice: iccprim: card 0
 Asynch Driver, V0.8b

Apparently this card is finicky about cabling. Have user
consult the ICC User Manual if they have problems with
terminals after the card is working. Also note that unlike
the asy driver for com ports, one can spawn a getty on an
ICC card port whether anything is connected to the port or not,
without getting a "getty respawning too rapidly" message.
If the driver is having problems with ICC ports, it is more
common to see an error 19 (no such device) when attempting to
turn on such a port.
