You can -dynamically create a new interface by saying 'mkdir /proc/comx/comx0' (or you -can name it whatever you want up to 8 characters long, comx[n] is just a -convention). -Generally the files contained in these directories are text files, which can -be viewed by 'cat filename' and you can write a string to such a file by -saying 'echo _string_ >filename'. This is very similar to the sysctl interface. -Don't use a text editor to edit these files, always use 'echo' (or 'cat' -where appropriate). -When you've created the comx[n] directory, two files are created automagically -in it: 'boardtype' and 'protocol'. You have to fill in these files correctly -for your board and protocol you intend to use (see the board and protocol -descriptions in this file below or the example scripts in the 'etc' directory). -After filling in these files, other files will appear in the directory for -setting the various hardware- and protocol-related informations (for example -irq and io addresses, keepalive values etc.) These files are set to default -values upon creation, so you don't necessarily have to change all of them. - -When you're ready with filling in the files in the comx[n] directory, you can -configure the corresponding network interface with the standard network -configuration utilities.

This protocol is a bit more complicated than the others, -because it allows to use 'subinterfaces' or DLCIs within one physical device. -First you have to create the 'master' device (the actual physical interface) -as you would do for other protocols. Specify 'frad' as protocol type. -Now you can bring this interface up by saying 'ifconfig comx0 up' (or whatever -you've named the interface). Do not assign any IP address to this interface -and do not set any routes through it. -Then, set up your DLCIs the following way: create a comx interface for each -DLCI you intend to use (with mkdir), and write 'dlci' to the 'boardtype' file, -and 'ietf-ip' to the 'protocol' file. Currently, the only supported -encapsulation type is this (also called as RFC1294/1490 IP encapsulation). -Write the DLCI number to the 'dlci' file, and write the name of the physical -COMX device to the file called 'master'. -Now you can assign an IP address to this interface and set routes using it. -See the example file for further info and example config script. -Notes: this driver implements a DTE interface with partially implemented -Q933a LMI. -You can find an extensively commented example in the 'etc' directory. - -FURTHER /proc FILES - -boardtype: -Type of the hardware.
