Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

This is the README for the Gracilis Packetwin device driver, version 0.5
|
|
ALPHA for Linux 1.3.43.
|
|
|
|
These files will allow you to talk to the PackeTwin (now know as PT) and
|
|
connect through it just like a pair of TNCs. To do this you will also
|
|
require the AX.25 code in the kernel enabled.
|
|
|
|
There are four files in this archive; this readme, a patch file, a .c file
|
|
and finally a .h file. The two program files need to be put into the
|
|
drivers/net directory in the Linux source tree, for me this is the
|
|
directory /usr/src/linux/drivers/net. The patch file needs to be patched in
|
|
at the top of the Linux source tree (/usr/src/linux in my case).
|
|
|
|
You will most probably have to edit the pt.c file to suit your own setup,
|
|
this should just involve changing some of the defines at the top of the file.
|
|
Please note that if you run an external modem you must specify a speed of 0.
|
|
|
|
The program is currently setup to run a 4800 baud external modem on port A
|
|
and a Kantronics DE-9600 daughter board on port B so if you have this (or
|
|
something similar) then you're right.
|
|
|
|
To compile in the driver, put the files in the correct place and patch in
|
|
the diff. You will have to re-configure the kernel again before you
|
|
recompile it.
|
|
|
|
The driver is not real good at the moment for finding the card. You can
|
|
'help' it by changing the order of the potential addresses in the structure
|
|
found in the pt_init() function so the address of where the card is is put
|
|
first.
|
|
|
|
After compiling, you have to get them going, they are pretty well like any
|
|
other net device and just need ifconfig to get them going.
|
|
As an example, here is my /etc/rc.net
|
|

|
This version of the driver comes under the GNU GPL. If you have one of my
|
|
previous (non-GPL) versions of the driver, please update to this one.
|
|
|
|
I hope that this all works well for you. I would be pleased to hear how
|
|
many people use the driver and if it does its job.
