RocketPort ISA and RocketModem II PCI boards are also supported by this RocketPort ISA and RocketModem II PCI boards currently are only supported by
driver, but must use the external module driver for configuration reasons. this driver in module form.
The RocketPort ISA board requires I/O ports to be configured by the DIP
switches on the board. See the section "ISA Rocketport Boards" below for
information on how to set the DIP switches.
You pass the I/O port to the driver using the following module parameters:
board1 : I/O port for the first ISA board
board2 : I/O port for the second ISA board
board3 : I/O port for the third ISA board
board4 : I/O port for the fourth ISA board
There is a set of utilities and scripts provided with the external driver
( downloadable from http://www.comtrol.com ) that ease the configuration and
setup of the ISA cards.
The RocketModem II PCI boards require firmware to be loaded into the card
before it will function. The driver has only been tested as a module for this
board.

ISA Rocketport Boards
---------------------
You must assign and configure the I/O addresses used by the ISA Rocketport
card before installing and using it. This is done by setting a set of DIP
switches on the Rocketport board.
SETTING THE I/O ADDRESS
-----------------------
Before installing RocketPort(R) or RocketPort RA boards, you must find
a range of I/O addresses for it to use. The first RocketPort card
requires a 68-byte contiguous block of I/O addresses, starting at one
of the following: 0x100h, 0x140h, 0x180h, 0x200h, 0x240h, 0x280h,
0x300h, 0x340h, 0x380h. This I/O address must be reflected in the DIP
switiches of *all* of the Rocketport cards.
The second, third, and fourth RocketPort cards require a 64-byte
contiguous block of I/O addresses, starting at one of the following
I/O addresses: 0x100h, 0x140h, 0x180h, 0x1C0h, 0x200h, 0x240h, 0x280h,
0x2C0h, 0x300h, 0x340h, 0x380h, 0x3C0h. The I/O address used by the
second, third, and fourth Rocketport cards (if present) are set via
software control. The DIP switch settings for the I/O address must be
set to the value of the first Rocketport cards.
In order to destinguish each of the card from the others, each card
must have a unique board ID set on the dip switches. The first
Rocketport board must be set with the DIP switches corresponding to
the first board, the second board must be set with the DIP switches
corresponding to the second board, etc. IMPORTANT: The board ID is
the only place where the DIP switch settings should differ between the
various Rocketport boards in a system.
The I/O address range used by any of the RocketPort cards must not
conflict with any other cards in the system, including other
RocketPort cards. Below, you will find a list of commonly used I/O
address ranges which may be in use by other devices in your system.
On a Linux system, "cat /proc/ioports" will also be helpful in
identifying what I/O addresses are being used by devics on your
system.
Remember, the FIRST RocketPort uses 68 I/O addresses. So, if you set it
for 0x100, it will occupy 0x100 to 0x143. This would mean that you
CAN NOT set the second, third or fourth board for address 0x140 since
the first 4 bytes of that range are used by the first board. You would
need to set the second, third, or fourth board to one of the next available
blocks such as 0x180.
