The next step is to install the software we need. The basic software is the irda-common package. This package offers some tools like irmanager or irattach that we need to configure our device.
You can also install the irda-tools package. This package has tools like irdadump or irdaping. They are very important tools for debugging and testing.
These packages, irda-common and irda-tools are available in the Debian GNU/Linux distribution and in other distributions too.
