Sun discontinued the old Java comm package for Windows. There's a substitute,
and a good one, available though: RXTX.

Did you actually *read* the home page of that RXTX site? Aren't you curious
to know what that mysterious 'download' link near the top of the page does?

Maybe you should have specified the exact co-ordinates of the download link.

Measured in pixels? inches? centimetres? lat/long? ;-) If this 'not reading'
continues I'm afraid a whole lot of questions are going to be posted about this
serial communication topic.

What's that? Never heard of it. Is it homoeopathic? ;-)

Nope, it's just bad for your eyes; elderly people, they say, have read quite a bit;
that's why they have very bad eyes; reading wears out your eye muscles, i.e.
you have to move your eyes from left to right all the time; very bad for your eyes.

Jos ;-)

Oh, that sounds awful! What can we do to prevent this from happening? I heard somewhere, that nowadays even small children are taught to read at school - shouldn't schools be sued for harming those young, innocent kids?

I tried with my which I did download first.
But some functions are not supported.
That's why I downloaded your's.
Now I get RXTXcomm.jar, and I dropped that into ext directory but Compiler says javax.comm.* does not exist.

Please Help!

Could you possibly have more than one ext directory? If you have one in your JRE and one in your JDK, then the compiler will probably look in that of the JDK but when running it you'll need it in the JRE...

Tut, tut, DJ, you really need to *read* what's on that site to be able to use their package. It's all there.

Have you read that RXTX uses another package name for copyright reasons?
btw, you also need to store two .dlls in your bin directory. Don't just dump files
all over the place and expect things to work automagically without reading at
least a few installation instructions.

What do you want to do with that serial port anyway?

That doesn't make sense: Sun doesn't have the RXTX package available for
download. What are you doing except making a mess out of your Java installation?

That is not true: the compiler doesn't look in the jdk's ext directory for anything.
Installing additional ext packages should only be installed in the jre's ext directory.

Oh, in that case I was misinformed. Never believe, what you read on the internet... ^^ But at least it works now.

If you're talking about the OP's problem: I sincerely doubt it: as I understand now,
the OP has an old Sun's version installed in his ext directory and one or more
dlls 'dropped' somewhere; who knows where he got the .dlls from.
