+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.
