-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 a /etc/modprobe.d/*.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.
