- 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

- /sbin/route add -host 44.136.8.95 dev pt0b
- /sbin/route add -host 44.255.255.255 dev pt0b
- 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.
