[Tinyos-help] serial forwards probelms on lesson 5

[BAI LI]

Hi All,

I am having problems with serial forwards. I am using telosb motes. when i
type

Administrator at baili /opt/tinyos-2.x/apps/Oscilloscope/java
$ java net.tinyos.sf.SerialForwarder

the serial forwarder window pops up but it didn't display any data only num
clinets changed to 1
here is the message displayed:

Could not open com1: TOSComm JNI library runtime error: Error 2.
   ϵͳÕҲ»µ½ָ¶¨µÄÎļþ¡£
   in NativeSerialPort.CreateFile
serial at com1:57600 died - restarting


When i type command like
Administrator at baili /opt/tinyos-2.x/apps/Oscilloscope/java
$ java net.tinyos.sf.SerialForwarder -comm sf at localhost:9002

it displayed on the serial forwarder interface like

Listening to sf at localhost:9002
Listening for client connections on port 9002

then got struck, nums clinents is also 1.

what probelms it might be? Sum1 told me telosb should go with mica together

this serial forwarder successfully?

It also happens to my
