A common problem that have to be mentioned in the documentation.
possible reasons:
1. if you are using SerialForwarder, make sure your problem is pointing
to the same port number, which SerialForwarder is outputing to.
you can start your SerialForwarder as
java net.tinyos.sf.SerialForwarder -port 9003 -comm serial@/dev/ttyS0:mica2
then you use use [EMAIL PROTECTED]:9003
2. if you tried to connect from other host rather than localhost, you
have to make sure the System-wide Environment Variable for "MOTECOM" is
set to whatever you desired to use.
i.e.: [EMAIL PROTECTED]:PORT
if you look into the TinyOS source code, you will found the JNI function
tries to get this variable using ENV.getenv("MOTECOM"). It binds to
default value ([EMAIL PROTECTED]:9002) when it can't resolve the variable.
for Mac Users, there is a tool, called "RCEnvironment", which allows you
to add system-wide environment variable (require reboot/logout to take
effect).

i try to compile the lesson 4 Mote Pc serial Communication and Serial
Forwarder :
When i execute java TestSerial, there is an error message wich appears :
[EMAIL PROTECTED]:9002 died - exiting (java.net.ConnectException: Connection
refused).
What platform? (Windows, Linux, Mac) Do you have a firewall? Have you set up
your motecom variable? What commands are you using to execute TestSerial?
Are you using the serial forwarder or not?
What version of TinyOS?
