| 1 | This is the README for the Gracilis Packetwin device driver, version 0.5 | ||
| 2 | ALPHA for Linux 1.3.43. | ||
| 3 | |||
| 4 | These files will allow you to talk to the PackeTwin (now know as PT) and | ||
| 5 | connect through it just like a pair of TNCs. To do this you will also | ||
| 6 | require the AX.25 code in the kernel enabled. | ||
| 7 | |||
| 8 | There are four files in this archive; this readme, a patch file, a .c file | ||
| 9 | and finally a .h file. The two program files need to be put into the | ||
| 10 | drivers/net directory in the Linux source tree, for me this is the | ||
| 11 | directory /usr/src/linux/drivers/net. The patch file needs to be patched in | ||
| 12 | at the top of the Linux source tree (/usr/src/linux in my case). | ||
| 13 | |||
| 14 | You will most probably have to edit the pt.c file to suit your own setup, | ||
| 15 | this should just involve changing some of the defines at the top of the file. | ||
| 16 | Please note that if you run an external modem you must specify a speed of 0. | ||
| 17 | |||
| 18 | The program is currently setup to run a 4800 baud external modem on port A | ||
| 19 | and a Kantronics DE-9600 daughter board on port B so if you have this (or | ||
| 20 | something similar) then you're right. | ||
| 21 | |||
| 22 | To compile in the driver, put the files in the correct place and patch in | ||
| 23 | the diff. You will have to re-configure the kernel again before you | ||
| 24 | recompile it. | ||
| 25 | |||
| 26 | The driver is not real good at the moment for finding the card. You can | ||
| 27 | 'help' it by changing the order of the potential addresses in the structure | ||
| 28 | found in the pt_init() function so the address of where the card is is put | ||
| 29 | first. | ||
| 30 | |||
| 31 | After compiling, you have to get them going, they are pretty well like any | ||
| 32 | other net device and just need ifconfig to get them going. | ||
| 33 | As an example, here is my /etc/rc.net | ||

| 52 | This version of the driver comes under the GNU GPL. If you have one of my | ||
| 53 | previous (non-GPL) versions of the driver, please update to this one. | ||
| 54 | |||
| 55 | I hope that this all works well for you. I would be pleased to hear how | ||
| 56 | many people use the driver and if it does its job. | ||
