| Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 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 |
| 34 | -------------------------- |

| 45 | # Configure the PackeTwin, port B. |
| 46 | /sbin/ifconfig pt0b 44.136.8.87 hw ax25 vk2xlz-1 mtu 512 |
| 47 | /sbin/ifconfig pt0b 44.136.8.87 broadcast 44.255.255.255 netmask 255.0.0.0 |
| 48 | /sbin/route add -host 44.136.8.216 dev pt0b |
| 49 | /sbin/route add -host 44.136.8.95 dev pt0b |
| 50 | /sbin/route add -host 44.255.255.255 dev pt0b |
| 51 | |
| 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. |
