Re: mkiss, udev and kernel 2.6

As I said in my original message to Bernard, it's not a hard thing. 
First, you have to make sure that BSD PTY support is in your kernel. 
Then, in your bootscripts, before you run the mkiss command to set up
the dual port TNC, create the 4 legacy PTY nodes into the /dev
filesystem.  You can find the correct major/minor numbers to use by
looking at devices.txt in the kernel source Doucmentation directory,
or looking at an old distro that has them set up already.  You'll need
4 device nodes:

/dev/ptyp0 - character device, major number 2, minor number 0
/dev/ptyp1 - character device, major number 2, minor number 1
/dev/ttyp0 - character device, major 3, minor 0
/dev/ttyp1 - character device, major 3, minor 1

Then, your mkiss command will look something like this:

mkiss -s 9600 /dev/ttyS0 /dev/ptyp0 /dev/ptyp1

and your kissattach commands will reference /dev/ttyp0 and /dev/ttyp1.
 On my Kam, when configured this way, /dev/ttyp0 ends up the VHF port,
and /dev/ttyp1 the HF port.

Hope this helps!
