| 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 | |
| -------------------------- | |
| # | |
| # Configure the PackeTwin, port A. | |
| /sbin/ifconfig pt0a 44.136.8.87 hw ax25 vk2xlz mtu 512 | |
| /sbin/ifconfig pt0a 44.136.8.87 broadcast 44.136.8.255 netmask 255.255.255.0 | |
| /sbin/route add -net 44.136.8.0 netmask 255.255.255.0 dev pt0a | |
| /sbin/route add -net 44.0.0.0 netmask 255.0.0.0 gw 44.136.8.68 dev pt0a | |
| /sbin/route add -net 138.25.16.0 netmask 255.255.240.0 dev pt0a | |
| /sbin/route add -host 44.136.8.255 dev pt0a | |
| # | |
| # Configure the PackeTwin, port B. | |
| /sbin/ifconfig pt0b 44.136.8.87 hw ax25 vk2xlz-1 mtu 512 | |
| /sbin/ifconfig pt0b 44.136.8.87 broadcast 44.255.255.255 netmask 255.0.0.0 | |
| /sbin/route add -host 44.136.8.216 dev pt0b | |
| /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. | |
