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
|
||
|
|
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.
