How to use the serial forwarder on testbed?

1. To open the serial forwarder on testbed, run the command

'forwarder.py -2 -a telosb'

2. We can get the packet format used by the serial forwarder in 'tospacket.py':

      0: Delimiter (0x7E)
      1: Protocol: ACK (0x43), PACKET_ACK (0x44) or PACKET_NOACK (0x45)
      2: Sequence number (omitted if protocol is PACKET_NOACK)
      3: Packet type (0x00, omitted if protocol is ACK)
      4: Destination high byte (omitted if protocol is ACK)
      5: Destination low byte (omitted if protocol is ACK)
      6: Source high byte (omitted if protocol is ACK)
      7: Source low byte (omitted if protocol is ACK)
      8: Payload length (omitted if protocol is ACK)
      9: Destination PAN group (omitted if protocol is ACK)
      10: Packet AM type (omitted if protocol is ACK)
      11 .. n-4: Payload (omitted if protocol is ACK)
      n-3: CRC-16 low byte
      n-2: CRC-16 high byte
      n-1: Delimiter (0x7E)
