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.

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.
