The Linux RocketPort 550 Drivers allow application space programs to perform asynchronous communications using boards from the Comtrol RocketPort 550 range. 1. Installing Your RocketPort 550 hardware Take care when you handle the RocketPort 550 PCI cards, like any electronic device, they are sensitive to static electricity. Use normal static precautions such as wearing an earth ground strap. Power down the host PC and disconnect its mains input. Follow the host PC instructio

2. Installing the RocketPort 550 Linux Device Driver software NOTE The Comtrol Linux driver release 1.03 was developed using the RED HAT 8.0 distribution with Kernel revision 2.4.18-14. The driver source is provided should developers wish or need to modify the driver for use with alternative Linux distributions and/or Kernels. For use with other 2.4.x kernels, a simple re-compilation (on the target system) is all that may be necessary and a ‘Makefile’ is provided to automate this

Step 2. Next, create a temporary directory into which the files can be extracted: [root@localhost root]# cd /tmp [root@localhost tmp]# mkdir inst_Comtrol [root@localhost tmp]# cd inst_Comtrol Step 3. Then, extract the driver components from the tar file on the diskette or CD ROM to the temporary directory: Note that the name of the tar file may be different.

There are two names for each port, one is for communication with a modem, the other is for communication with a terminal or computer Usually the modem connection has a Device name like 'cuaa..' and the terminal/computer connection has a name such as 'ttyA..' See section 6 for more information about port naming. You are prompted to enter the Special Device name prefix for terminal ports: Please enter the Special Device name for terminals [....] 7

4. Driver Removal There is generally no need to remove the device driver from the system. If a card is no longer required, simply shutdown and power off the computer, remove the card and reboot the system. If there are no longer any installed cards then the driver will detect this condition unload itself. However, the driver files will remain installed on the system’s hard disk. At a later time the RocketPort 550 card(s) can be re-installed and the computer restarted. The drivers

6. Port Names The following tables show the port names given to each RocketPort 550 port if you choose the ‘normal’ cuaa and ttyA naming. Modem Devices Port First Board Second Board Third Board Fourth Board /dev/cuaa00 /dev/cuaa16 /dev/cuaa32 /dev/cuaa48 1 /dev/cuaa01 /dev/cuaa17 /dev/cuaa33 /dev/cuaa49 2 /dev/cuaa02 /dev/cuaa18 /dev/cuaa34 /dev/cuaa50 3 /dev/cuaa03 /dev/cuaa19 /dev/cuaa35 /dev/cuaa51 4 /dev/cuaa04 /dev/cuaa20 /dev/cuaa36 /dev/cuaa52 5 /dev/cuaa05 /dev/cuaa

Also, note that the assigned special device names are fixed as shown in the above tables. So, the first RocketPort will start at /dev/ttyA00, the second at /dev/ttyA16 and so on, regardless of whether the RocketPorts are 4, 8 or 16 port examples. For example, if installing, say, two 8 port RocketPorts then the first card will use device names /dev/ttyA00 to /dev/ttyA07 and the second board will use /dev/ttyA16 to /dev/ttyA23. Of course two 16 port controllers will have sixteen contigu

7. RocketPort 550 Linux driver (re)compilation Before compiling the RocketPort 550 driver, you must install the Linux kernel source code. Consult Linux on-line documentation and/or web hosted Linux documentation for the procedure. With the RED HAT Linux 8.0 boxed set distribution, the Linux kernel source is provided in a format ready for installation using RPM. Following successful installation of the kernel source code, the kernel source tree root will be found at /usr/src/linux2.4
