There is a need for a text about networking in general. I do not
know enough to write it myself.
By the way, the source code package contains text files that
may contain relevant information:

That is because you normally want an error free link between
two (and two only) computers.

Oooh! You are an old man.....
Look at the young ones. They turn and click wildly and expect to
be guided by feedback from the computer:-)

This is doable. I could put the address that MAP65 wants if someone
will remind me what it is.
The default would still be the same, but by typing -1 instead of
something in the range 0 to 15 the address would be fetched from

Yes. That would be very good. Something about networks in general. With
a focus on local networks and some information about how packets
pass through switches. I think the default address of Linrad would
propagate to every computer on a local network through all switches
while packages on the MAP65 addres would only reach those parts
of a network that are needed th transfer data between the desired
computers. I really do not know, but I hope someone else will
be able to write something about this.

Well, I have written quite a lot of text that it seems nobody is reading.
By writing more about the wrong things I would only hide the important
information in "noise" There is a limit in how much people can read
without loosing interest.

That is true. Someone suggested this brilliant idea to me. I actually
never hit my mind before.

Well, it is certainly true - and I do need the pushes to be able to
understand what is creating problems.

But why? I try to create an interest in using Linrad for various
purposes. It is really easy to download and unzip the 3 files needed
for Windows. Unfortunately there is no installer with a beautiful
icon to place on the desktop, but that is because I have no idea how
to create such a thing.
I have had a feedback from someone who was not able to unpack
the zip file and type linrad in the command window and he would
have been helped by an installer. Maybe someone can help?

This would be excellent. Meanwhile I will make changes whenever
appropriate to make Linrad behave in a way that makes as much as
possible of the information needless. (But it would have to

Absolutely. The idea is that you should find all the information
in Linrad itself after having read the newcomers page:
By selecting 'N' as the first keypress when starting Linrad for
the first time you will start in "newcomer mode." This way it
should be rather easy for a newcomer to get a working system
because many parameters will silently be set to default values.

OK. Please start with a first question by describing shortly at what
point something is unclear. (And how you got to that point.)
Perhaps we can arrive at some modification I can do in Linrad or
in the Linrad for newcomers page that would solve the issue.
In some cases that would not be possible because your questions
may be related to a particular hardware (or to MAP65) and then
there might be a need for an answer in your particular situation.
If someone could write a text that would fit on a single screen
I could add it in the help file so one coulöd press F1 to read it
during the network setup. Together with default files for
par_netsend_ip and par_netrec_ip it seems to me that the problems
you have encountered with network setup should be solved.
