Computone Intelliport II/Plus Multiport Serial Driver
-----------------------------------------------------
-Release Notes For Linux Kernel 2.2
-These notes have been tested on Linux kernels 2.0 and 2.2.
-
-Please refer to Documentation/computone.txt for information on the driver
-that is included with the kernel sources.
-
-
-Version: 1.2.9
-Date: 04/12/2000
-Fixes and Updates: Doug McNash
-Historical Author: Andrew Manison
-Kernel Integration: Mike Warfield <mhw@wittsend.com>
-
-1. INTRODUCTION
-
-This driver supports the entire family of Intelliport II/Plus controllers
-with the exception of the MicroChannel controllers.
-
-This driver was developed on the v2.0.x Linux source tree and has been
-tested up to v2.2.14; it will probably not work with earlier v1.X kernels,
-and has not yet been tested on the v2.1.x tree. The most likely problems
-will be in patching the kernel sources to support the driver. For this
-reason there are 2 different patch files for 2.0.XX and 2.2.XX kernels.
-Make sure you use the right one!
-Note that a version (1.2.5) is included in the 2.2.12+ kernels so this
-will not be a new install but and upgrade.
-
-
-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 that free
- address. You may need to configure your BIOS to reserve the
- irq for the ISA card. PCI and EISA parameters are set
- automagically and need only be set to nonzero values.
- Insert card into computer with the power off before or after
- driver installation.
-
-Software - New Installation
-
-Module installation:
-
-a) Obtain driver-kernel patch file
-b) Copy to the linux source tree root, Run ip2build (if not patch)
-c) Determine free irq/address to use if any (configure BIOS if need be)
-d) 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.
-e) Set address on ISA cards then:
- edit /usr/src/linux/drivers/char/ip2/ip2.h if needed
- or
- edit /etc/modules.conf if needed (module).
- or both to match this setting.
-f) Run "make dep"
-g) Run "make modules"
-h) Run "make modules_install"
-i) Run "/sbin/depmod -a"
-i) install driver using `modprobe ip2 <options>` (options listed below)
-j) run mkip2dev
-
-
-Kernel installation:
-
-a) Obtain driver-kernel patch file
-b) Copy to the linux source tree root, Run ip2build (if not patch)
-c) Determine free irq/address to use if any (configure BIOS if need be)
-d) 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.
-e) Set address on ISA cards then:
- edit /usr/src/linux/drivers/char/ip2/ip2.h
-f) Run "make dep"
-g) Run "make zImage" or whatever target you prefer.
-h) mv /usr/src/linux/arch/i386/boot/zImage to /boot.
-i) add new config for this kernel into /etc/lilo.conf, run "lilo"
-j) reboot using this kernel
-k) make and run ip2/mkip2dev
-
-Software - Upgrades
-
-a) Install new sources in proper location, usually /usr/src/linux/drivers/char
-b) Follow steps above to create new kernel or modules
-
-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 the drivers source may be
-a tar file, then untar and run ip2build if a new installation.
-
-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.h 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/ip2.h (which
-selects polled mode). The io addresses are set to io=1 for PCI cards,i
-io=2 for EISA cards or io=[some valid ISA address] for ISA cards. If no
-base addresses are specified the defaults in ip2.h 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/ip2.h and recompile or just insert
-an options line in /etc/modules.conf or both. The command line takes
-precidence over the options line which takes precidence over the defaults
-in ip2.h.
-
-command line sample:
-
- modprobe ip2 io=1,0x328 irq=1,10
-
-/etc/modules.conf sample:
-
- options ip2 io=1,0x328 irq=1,10
- alias char-major-71 ip2
- alias char-major-72 ip2
- alias char-major-73 ip2
-
-the equivelant ip2.h:
-
-static ip2config_t ip2config =
-{
- {1,10,0,0},
- {
- 0x0001, // Board 0, ttyF0 - ttyF63 /* PCI card */
- 0x0328, // Board 1, ttyF64 - ttyF127 /* ISA card */
- 0x0000, // Board 2, ttyF128 - ttyF191 /* empty */
- 0x0000 // Board 3, ttyF192 - ttyF255 /* empty */
- }
-};
-
-Specifying an invalid or in-use ISA 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. Note that the PCI will be
-assigned it's irq by the BIOS and may not match what you specify.
-It must be non-zero otherwise it will be polled.
-
-Tarball Install:
-
-The whole tarfile should be untarred in the /usr/src/linux/drivers/char/
-directory. Most files required for the driver are placed in the ip2
-subdirectory. Then execute the script (for a new install only)
-
- ip2build
-
-which will patch the files.
-
-Kernel Patch Install:
-
- cd to the Linux source root, run patch -p1 < ThePatchFile.
-
-Now return to the root directory of the Linux
-source tree and run make config or make menuconfig. You will be prompted
-for the Computone drivers, either as a module or part of the kernel.
-If you have a PCI card you many need to select PCI bios support (CONFIG_PCI)
-if not enabled already. Ditto for CONFIG_MODULES if you use modules.
-
-If you select the driver as part of the kernel run :
-
- make depend
- make bzImage(,zlilo or whatever you do to create a bootable kernel)
-
-If you selected a module run :
-
- make modules && make modules_install
-
-The utility ip2mkdev 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. Note that the callout devices are going away in the
-future and that is what the warning messages are trying to tell you.
-
-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/expantion
-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. 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.
-
-Some installations report that characters fail to echo immediatly at a
-terminal if the kernel/modules are compiled with the CONFIG_M386 and
-the card is run in polling mode on a pentium class machine. Compiling
-with a more appropriate processor flag or running on interrupt would be
-the fix as well as the wise thing to do.
