I'm cc'ing back to the help list in case someone is better at this than me...
I'm not sure what all you are doing, or what the "terminal" software
and "run.sh" is. MicaHWVerify, and it's Java PC client do send messages
in both directions -- a request from PC and a reply from the mote. So
if it worked, then your hardware is OK.
The error messages you show indicate that you are trying to make a network
connection to a SerialForwarder program. SF acts as an (pointless and confusing
IMHO) intermediary between the PC serial port (assuming you are not using
the ethernet base station) and the rest of the world. If what you are trying
to do is connect directly to the serial port, you probably need to look at
the value of your MOTECOM environment variable. You can find all sorts of
useful information about this in the tutorial and via google.
I set this variable for using mica2's on a USB->serial converter as:
export MOTECOM="[EMAIL PROTECTED]:mica2"

Hi again!
First of all... thank you very much for your help with this issue...
We have successfully programmed our mote. And we have passed the
MicaHWVerify correctly. So it seems that both Mica, and Mica to PC
connection is working... but not the other way round(PC to Mica).
To send data from PC to Mica we have used the "terminal" software...
provided by crossbow in the installation CD. we think baud rate and
message format are ok, because in the communication from Mote to PC it
works...
The program downloaded in the mote to transmit and receive is the TOSBase.
We have followed the steps of the document you sent to us to test our
system... but when we execute the script run.sh we get this error:
Exception in thread "main" java.net.ConnectException: Connection

Do you know why we get this problem? we have litle experience in Java
programming...
Thank you very much again for all your help!!
