-Computone Intelliport II/Plus Multiport Serial Driver
------------------------------------------------------
-
-Release Notes For Linux Kernel 2.2 and higher.
-These notes are for the drivers which have already been integrated into the
-kernel and have been tested on Linux kernels 2.0, 2.2, 2.3, and 2.4.
-
-Version: 1.2.14
-Date: 11/01/2001
-Historical Author: Andrew Manison <amanison@america.net>
-Primary Author: Doug McNash
-
-This file assumes that you are using the Computone drivers which are
-integrated into the kernel sources.  For updating the drivers or installing
-drivers into kernels which do not already have Computone drivers, please
-refer to the instructions in the README.computone file in the driver patch.
-
-
-1. INTRODUCTION
-
-This driver supports the entire family of Intelliport II/Plus controllers
-with the exception of the MicroChannel controllers.  It does not support
-products previous to the Intelliport II.
-
-This driver was developed on the v2.0.x Linux tree and has been tested up
-to v2.4.14; it will probably not work with earlier v1.X kernels,.
-
-
-2. QUICK INSTALLATION
-
-Hardware - If you have an ISA card, find a free interrupt and io port. 
-		   List those in use with `cat /proc/interrupts` and 
-		   `cat /proc/ioports`.  Set the card dip switches to a free 
-		   address.  You may need to configure your BIOS to reserve an
-		   irq for an ISA card.  PCI and EISA parameters are set
-		   automagically.  Insert card into computer with the power off 
-		   before or after drivers installation.
-
-	Note the hardware address from the Computone ISA cards installed into
-		the system.  These are required for editing ip2.c or editing
-		/etc/modprobe.d/*.conf, or for specification on the modprobe
-		command line.
-
-	Note that the /etc/modules.conf should be used for older (pre-2.6)
-		kernels.
-
-Software -
-
-Module installation:
-
-a) Determine free irq/address to use if any (configure BIOS if need be)
-b) Run "make config" or "make menuconfig" or "make xconfig"
-   Select (m) module for CONFIG_COMPUTONE under character
-   devices.  CONFIG_PCI and CONFIG_MODULES also may need to be set.
-c) Set address on ISA cards then:
-   edit /usr/src/linux/drivers/char/ip2.c if needed 
-	or
-   edit config file in  /etc/modprobe.d/ if needed (module).
-	or both to match this setting.
-d) Run "make modules"
-e) Run "make modules_install"
-f) Run "/sbin/depmod -a"
-g) install driver using `modprobe ip2 <options>` (options listed below)
-h) run ip2mkdev (either the script below or the binary version)
-
-
-Kernel installation:
-
-a) Determine free irq/address to use if any (configure BIOS if need be)
-b) Run "make config" or "make menuconfig" or "make xconfig"
-   Select (y) kernel for CONFIG_COMPUTONE under character
-   devices.  CONFIG_PCI may need to be set if you have PCI bus.
-c) Set address on ISA cards then:
-	   edit /usr/src/linux/drivers/char/ip2.c  
-           (Optional - may be specified on kernel command line now)
-d) Run "make zImage" or whatever target you prefer.
-e) mv /usr/src/linux/arch/x86/boot/zImage to /boot.
-f) Add new config for this kernel into /etc/lilo.conf, run "lilo"
-	or copy to a floppy disk and boot from that floppy disk.
-g) Reboot using this kernel
-h) run ip2mkdev (either the script below or the binary version)
-
-Kernel command line options:
-
-When compiling the driver into the kernel, io and irq may be
-compiled into the driver by editing ip2.c and setting the values for
-io and irq in the appropriate array.  An alternative is to specify
-a command line parameter to the kernel at boot up.
-
-        ip2=io0,irq0,io1,irq1,io2,irq2,io3,irq3
-
-Note that this order is very different from the specifications for the
-modload parameters which have separate IRQ and IO specifiers.
-
-The io port also selects PCI (1) and EISA (2) boards.
-
-        io=0    No board
-        io=1    PCI board
-        io=2    EISA board
-        else    ISA board io address
-
-You only need to specify the boards which are present.
-
-        Examples:
-
-                2 PCI boards:
-
-                        ip2=1,0,1,0
-
-                1 ISA board at 0x310 irq 5:
-
-                        ip2=0x310,5
-
-This can be added to and "append" option in lilo.conf similar to this:
-
-        append="ip2=1,0,1,0"
-
-
-3. INSTALLATION
-
-Previously, the driver sources were packaged with a set of patch files
-to update the character drivers' makefile and configuration file, and other 
-kernel source files. A build script (ip2build) was included which applies 
-the patches if needed, and build any utilities needed.
-What you receive may be a single patch file in conventional kernel
-patch format build script. That form can also be applied by
-running patch -p1 < ThePatchFile.  Otherwise run ip2build.
- 
-The 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. If the driver is built 
-into the kernel you will need to edit the file ip2.c to match the boards 
-you are installing. See that file for instructions. If the driver is 
-installed as a module the configuration can also be specified on the
-modprobe command line as follows:
-
-	modprobe ip2 irq=irq1,irq2,irq3,irq4 io=addr1,addr2,addr3,addr4
-
-where irqnum is one of the valid Intelliport II interrupts (3,4,5,7,10,11,
-12,15) and addr1-4 are the base addresses for up to four controllers. If 
-the irqs are not specified the driver uses the default in ip2.c (which 
-selects polled mode). If no base addresses are specified the defaults in 
-ip2.c are used. If you are autoloading the driver module with kerneld or
-kmod the base addresses and interrupt number must also be set in ip2.c
-and recompile or just insert and options line in /etc/modprobe.d/*.conf or both.
-The options line is equivalent to the command line and takes precedence over
-what is in ip2.c. 
-
-config sample to put /etc/modprobe.d/*.conf:
-	options ip2 io=1,0x328 irq=1,10
-	alias char-major-71 ip2
-	alias char-major-72 ip2
-	alias char-major-73 ip2
-
-The equivalent in ip2.c:
-
-static int io[IP2_MAX_BOARDS]= { 1, 0x328, 0, 0 };
-static int irq[IP2_MAX_BOARDS] = { 1, 10, -1, -1 }; 
-
-The equivalent for the kernel command line (in lilo.conf):
-
-        append="ip2=1,1,0x328,10"
-
-
-Note:	Both io and irq should be updated to reflect YOUR system.  An "io"
-	address of 1 or 2 indicates a PCI or EISA card in the board table.
-	The PCI or EISA irq will be assigned automatically.
-
-Specifying an invalid or in-use irq will default the driver into
-running in polled mode for that card.  If all irq entries are 0 then
-all cards will operate in polled mode.
-
-If you select the driver as part of the kernel run :
-
-	make zlilo (or whatever you do to create a bootable kernel)
-
-If you selected a module run :
-
-	make modules && make modules_install
-
-The utility ip2mkdev (see 5 and 7 below) creates all the device nodes
-required by the driver.  For a device to be created it must be configured
-in the driver and the board must be installed. Only devices corresponding
-to real IntelliPort II ports are created. With multiple boards and expansion
-boxes this will leave gaps in the sequence of device names. ip2mkdev uses
-Linux tty naming conventions: ttyF0 - ttyF255 for normal devices, and
-cuf0 - cuf255 for callout devices.
-
-
-4. USING THE DRIVERS
-
-As noted above, the driver implements the ports in accordance with Linux
-conventions, and the devices should be interchangeable with the standard
-serial devices. (This is a key point for problem reporting: please make
-sure that what you are trying do works on the ttySx/cuax ports first; then 
-tell us what went wrong with the ip2 ports!)
-
-Higher speeds can be obtained using the setserial utility which remaps 
-38,400 bps (extb) to 57,600 bps, 115,200 bps, or a custom speed. 
-Intelliport II installations using the PowerPort expansion module can
-use the custom speed setting to select the highest speeds: 153,600 bps,
-230,400 bps, 307,200 bps, 460,800bps and 921,600 bps. The base for
-custom baud rate configuration is fixed at 921,600 for cards/expansion
-modules with ST654's and 115200 for those with Cirrus CD1400's.  This
-corresponds to the maximum bit rates those chips are capable.  
-For example if the baud base is 921600 and the baud divisor is 18 then
-the custom rate is 921600/18 = 51200 bps.  See the setserial man page for
-complete details. Of course if stty accepts the higher rates now you can
-use that as well as the standard ioctls().
-
-
-5. ip2mkdev and assorted utilities...
-
-Several utilities, including the source for a binary ip2mkdev utility are
-available under .../drivers/char/ip2.  These can be build by changing to
-that directory and typing "make" after the kernel has be built.  If you do
-not wish to compile the binary utilities, the shell script below can be
-cut out and run as "ip2mkdev" to create the necessary device files.  To
-use the ip2mkdev script, you must have procfs enabled and the proc file
-system mounted on /proc.
-
-
-6. NOTES
-
-This is a release version of the driver, but it is impossible to test it
-in all configurations of Linux. If there is any anomalous behaviour that 
-does not match the standard serial port's behaviour please let us know.
-
-
-7. ip2mkdev shell script
-
-Previously, this script was simply attached here.  It is now attached as a
-shar archive to make it easier to extract the script from the documentation.
-To create the ip2mkdev shell script change to a convenient directory (/tmp
-works just fine) and run the following command:
-
-	unshar Documentation/serial/computone.txt
-		(This file)
-
-You should now have a file ip2mkdev in your current working directory with
-permissions set to execute.  Running that script with then create the
-necessary devices for the Computone boards, interfaces, and ports which
-are present on you system at the time it is run.
