2. PCMCIA Installation

This section gives a very cursory overview of the installation of PCMCIA package over

Linux. If you know that you are going to be using PCMCIA hardware, it is best to

configure that in your kernel when you are installing Linux initially. In our case, we had

done so and had put the PCMCIA package included in the RedHat 6.1 kernel v2.2.12 on

our system.

For the SBC, the PCMCIA drivers came pre-installed from EMAC.

2.1 Files

The PCMCIA package on our system needed to be upgraded to a newer version because

the newer version had support for the Lucent WaveLAN cards that we were using. The

latest version is the pcmcia-cs-3.1.22 and it has support for most wireless LAN cards. In

addition it has much needed wireless extensions that can be used to configure the device.

2.2 Wireless Extensions and support

Along with the PCMCIA package, you also need the wireless extensions. The usage of

the extensions is such:

Wireless_tools.19 : are used with Kernel version before 2.2.14

Wireless_tools.20 : are used with Kernel version 2.2.14 and later

There are three main tools in the package.

2.2.1 iwconfig

This tool is designed to configure all the wireless specific parameters of the driver and

the hardware. This is a clone of ifconfig used for standard device configuration.

2.2.2 iwspy

This tool allows the user to set a list of network addresses in the driver. The driver will

gather quality information for each of those addresses (updated each time it receives a

packet from that address). The tool allows the user to display the information associated

with each address in the list.

2.2.3 iwpriv
