[TinyOS-Help]: Surge.Mainclass error & when staring SerialForwarder, how to set the baud rate??

[Renee Azhen]

Dear all:
  I want to use tossim to simulate the Surge application, but faced two problems:
  1. when staring SerialForwarder, how to set the baud rate??  I am using a   
      laptop
  here is the command:
  java net.tinyos.sf.SerialForwarder -comm serial at COM1:<baud rate>
  2. I use the default baud rate, 19200, but when start the Java application Sure.Mainclass, an error occured, here is the screening shot:
  C:\Program Files\UCB\cygwin\opt\tinyos-1.x\tools\java>java net.tinyos.surge.Main
Class 125
Using AM group ID 125 (0x7d)
Starting mote listener...

  Dear all, could you help me to resolve these two problems??
  really thanks
