[FADCA] Fwd: 6pack query

[Chuck Hast]

Here is some good news for those of us who are using 6pack, one of
the positive points of 6pack was the ability to talk to multiple TNC's off
of a single serial port, until now we were told that the Linux version did
not yet have the ability to talk to more than one TNC/port, now we have
the fix, as soon as I can free up some time, I will get it tested, this will
allow locations that may be port challenged to have up to 4 tnc's/ port
which makes a laptop or some other one or two port device much more
attractive.

In fact, I implemented it years ago in userspace. I don't know why,
but the ax25-utils maintainers never put it on the stock version (even
though I sent them the patch).

Get a copy of ax25-tools-0.0.8 from ax25.sourceforge.net, and save it
somewhere (say /home/myuser/ax25-tools/). Get a copy of my patch from:

   http://www.escomposlinux.org/iarenaza/hamradio/m6pack/files/ax25-tools-0.0.8-m6pack.diff.bz2

and save it in the same directory. Now untar the tools and patch them:

        cd /home/myuser/ax25-tools
        tar xzf ax25-tools-0.0.8.tar.gz
        bzip2 -dc ax25-tools-0.0.8-m6pack.diff.bz2 | patch -p0

and build the m6pack binaries (you have to build libax25 previously,
or have it installed somewhere in your system --maybe it's the package
called libax25-dev--):

        cd ax25-tools-0.0.8
        ./configure
        cd kiss
        make m6pack

now you've got a new executable, called m6pack (and it's associated
manual page).

Now, let's suppose you've got your 6pack TNC ring attached to
/dev/ttyS0 and your TNCs are configured for 19200 bps on the serial
port. You've got 4 TNCs on your ring, so you execute:

   m6pack -s 19200 /dev/ttyS0 /dev/ptyq0 /dev/ptyq1 /dev/ptyq2 /dev/ptyq3

This "splits" your 4 TNC ring into 4 separate "pseudo-ports", each one
talking to a different TNC on your ring.

Now you use spattach to attach each one of them. Let's supppose your
radio ports (as configured in axports file) are called 6pack0, 6pack1,
etc:

    spattach /dev/ttyq0 6pack0
    spattach /dev/ttyq1 6pack1
    spattach /dev/ttyq1 6pack2
    spattach /dev/ttyq1 6pack3

- From here on, everything works the same as usual.
