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 electr onic 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 instructions for access to the PC and the installation of additional

cards.
You may install up to 4 RocketPort 550 PCI cards in one PC.

Ensure the front panel retaining screws are fitted.
Follow the host PC instructions for re assembly of the host PC its cabling and re-fitting

of safety covers.
Re-connect the host PC mains input, power up the PC and login as root.

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 process. Before (re)compilation, the kernel
source must be installed.

For test purposes, the driver source was (re)compiled under Red Hat 7.3 kernel 2.4.18-3.
The driver module was installed and functioned correctly.

This driver source will not (re)compile under the obsolete 2.2.x kernels. If it is wished to
use the RocketPort 550 with these earlier kernels, then request a copy of the RocketPort
550 Linux driver release 1.00.

The installation media (i.e. what you are installing from) may be a 1.44Mb floppy diskette or a
CD -ROM. Alternatively, you may have downloaded the driver from

http://www.comtrol.com

There may be minor differences in the installation procedure depending on the
installation media.

If you have downloaded the driver from http://www.comtrol.com, then it is suggested
that you copy the ‘tar’ file to an MS-DOS formatted floppy diskette and follow the
floppy disk based installation procedure

Following download, you may need to unzip the downloaded file in order to obtain the tar file. The tar
file name will be of the format relXXX.tar where XXX is the release number. E.g. XXX = 103 =
release 1.03

The following assumes that you have booted Linux and logged in as root.

Step 1

Extract the files from the installation media. First insert the floppy diskette or
CD into the relevant drive and mount the media so that the file can be accessed.

DISKETTE

[root@localhost root]# mount - t msdos /dev/fd0 /mnt/floppy

CD ROM

[root@localhost root]# mount /dev/cdrom /mnt/cdrom

4

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.

DISKETTE

[root@localhost inst_Comtrol]# tar xvf /mnt/floppy/rel103.tar

CD ROM

[root@localhost inst_comtrol]# tar xvf /mnt/cdrom/rel103.tar

Note:The path to rel103.tar may differ on the CD ROM.

Step 4

Run the installation script

IMPORTANT

If your Linux kernel is not version 2.4.18-14 or your kernel configuration
differs from our development system then you will need to (re)compile the
RocketPort 550 driver source on your system, otherwise the Install script will
display error messages and the driver will not be installed. If this is the case
then follow the procedure in section 7 , ( Re)-compiling the RocketPort 550
Linux driver, before proceeding with installation step 4.

5

Run the install script from the directory into which the files were extracted:

[root@localhost inst_Comtrol]# ./install

===========================================================

Comtrol Europe RocketPort 550 Drivers installation

Version 1.03

January 2003

===========================================================

Press Enter to begin installation

Press enter to begin installation.

A screen of text is displayed. It contains information about the names you can
select for the RocketPort 550 ports and details how the driver assigns numbers to
individual ports.

Your system will connect to the RockPort 550 Ports through entries

in the /dev/ directory. You can choose any prefix for the names,

as long as it is different from names given to other devices.

For example, if you select a prefix of 'ttyA', then the Rocket Port 550

Ports will be called /dev/ttyA00, /dev/ttyA01 and so on up to

/dev/ttyA63

You can install up to 4 RocketPort 550 cards in a system. The device names

for the first card starts with ttyA00, the second starts ttyA16, the third

ttyA32, and the fourth ttyA48. If the installed cards have less than

16 ports, then there will be gaps in the numbering corresponding to the

missing ports.

6

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

… and for modem ports:

Please enter the Special Device name for modems [....]

The installation script now copies the driver file into the module directory and
adds a command to initialisation scripts so that the driver is loaded whenever
Linux is rebooted.

Copying files ......Done

Adding insmod command to /etc/rc... directories...Done

Next, you are asked if you want to load the drivers now. If you have already fitted
the RocketPort 550 cards into the system (as we suggest you do), then you should
choose ‘Y’ here.

If you have not installed the cards yet, or have other administration tasks that will
need a reboot, you can say ‘N’ for no.

Do you want to install t he RocketPort module now. If you don't do it

now, then you will have to reboot before the serial ports can be

used.

Please enter [Y]es or [N]o [.]

If you say Yes, and you’re running on the System Console (not in X-Windows),
then you’ll see messages from the RocketPort 550 driver confirming that it has
successfully loaded and listing any boards it detects

Rckt550: Direct MAJOR is 253, callout is 252.

. Changing Configurations

It is not necessary to re -install the driver if you change the number of
RocketPort 555 cards in the system. Each time the system is restarted, the
boards are re -scanned and the Special Device files re-created.

9

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 will detect and operate the card(s).

5. Application Programming

The Application Programming Interface pertaining to the RocketPort 550 Linux
device driver is described in the Linux documentation for serial (tty) ports.

11

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 six teen contiguous device names from
/dev/ttyA00.

12

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.xx.yy
where xx = sub level and yy=extra version

For example for the source distributed with the Red Hat 8.0 boxed distribution the path
would be:-

/usr/src/linux2.4.18 -14

This will differ for other distributions and kernels and may even differ with localised RED HAT
Linux 8.0 distributions.

By way of another example, for Red Hat 7.3 boxed distribution the path would be:-

/usr/src/linux2.4.18 -3

Compilation procedure

For the purposes of this example, it is assumed that the compilation is on a system with
kernel revision 2.4.18-14

1. Make the symbolic link
[root@localhost root] # cd /usr/src
[root@localhost src] # ln –s linux-2.4.18 -14 linux

2. Navigate to the RocketPort 550 installaton directory because this contains the
Source, rckt550.c and the makefile (this document assumes that this is
/tmp/inst_comtrol.

[root@localhost src] # cd /tmp/inst_comtrol

3. Perform the compilation.
[root@localhost inst_comtrol] # make clean
[root@localhost inst_comtrol] # make

If the make is successful and error free then a new rckt550.o will be produced.

You can now use the ‘install’ script to install the driver, return to installation step 4.
