Hi Kaspar,

I have not done any experimenting with Data Streams yet since I can get by
with bytes.
I have tried both the RCXPort and the RCXF7Port. The big advantage of the
RCXPort using the LLC protocol is that if the RCX gets out of range or
behind an obstacle, the communication resumes when it can see the tower.
In my experiments, there is not much difference in speed. I get about 64
single byte messages (round trip) in about 1 minute from either version.
But even with the RCX facing the tower about a foot away, reliability is
still a problem. I have not been able to identify exactly where in my code
things go wrong, but only about half of my attempts at 64 round trip
messages are completed.
Sorry I can't shed much light on your problem.
Good luck,
Roger

| Ok, here's a little something to think about: I have been testing the three communication protocol stacks of LeJOS 2.0 (josx.rcxcomm package; LLC, LNP and F7 protocols). Simple application: Array (size 20) of ints on both PC and RCX. Got both a (...) (22 years ago, 10-Sep-02, to lugnet.robotics.rcx.java)
