 Comtrol(tm) RocketPort(R)/RocketModem(TM) Series
 Device Driver for the Linux Operating System

 =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

 PRODUCT OVERVIEW
 ----------------

 This driver provides a loadable kernel driver for the Comtrol RocketPort
 and RocketModem PCI boards. These boards provide, 2, 4, 8, 16, or 32
 high-speed serial ports or modems.  This driver supports up to a combination
 of four RocketPort or RocketModems boards in one machine simultaneously.
 This file assumes that you are using the RocketPort driver which is
 integrated into the kernel sources.

 The driver can also be installed as an external module using the usual
 "make;make install" routine.  This external module driver, obtainable
 from the Comtrol website listed below, is useful for updating the driver
 or installing it into kernels which do not have the driver configured
 into them.  Installations instructions for the external module
 are in the included README and HW_INSTALL files.

 RocketPort ISA and RocketModem II PCI boards currently are only supported by
 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.

 INSTALLATION PROCEDURES
 -----------------------

 RocketPort/RocketModem PCI cards require no driver configuration, they are
 automatically detected and configured.

 The RocketPort driver can be installed as a module (recommended) or built
 into the kernel. This is selected, as for other drivers, through the `make config`
 command from the root of the Linux source tree during the kernel build process.

 The RocketPort/RocketModem serial ports installed by this driver are assigned
 device major number 46, and will be named /dev/ttyRx, where x is the port number
 starting at zero (ex. /dev/ttyR0, /devttyR1, ...).  If you have multiple cards
 installed in the system, the mapping of port names to serial ports is displayed
 in the system log at /var/log/messages.

 If installed as a module, the module must be loaded.  This can be done
 manually by entering "modprobe rocket".  To have the module loaded automatically
 upon system boot, edit the /etc/modprobe.conf file and add the line
 "alias char-major-46 rocket".

 In order to use the ports, their device names (nodes) must be created with mknod.
 This is only required once, the system will retain the names once created.  To
 create the RocketPort/RocketModem device names, use the command
 "mknod /dev/ttyRx c 46 x" where x is the port number starting at zero.  For example:

 >mknod /dev/ttyR0 c 46 0
 >mknod /dev/ttyR1 c 46 1
 >mknod /dev/ttyR2 c 46 2

 The Linux script MAKEDEV will create the first 16 ttyRx device names (nodes)
 for you:

 >/dev/MAKEDEV ttyR

 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
 switches 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 distinguish 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 devices 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.
