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. + + - Craig vk2xlz <csmall@small.dropbear.id.au> |
