tos-serial-debug [serial port] [baud rate]
tos-serial-debug is a tool that reads raw bytes from a serial port and prints them to stdout in hexidecimal format. It is typically used to determine whether failure to communicate with a node over the serial port is due to an inability to receive anything or whether it is due to disagreement on the packet format.
tos-serial-debug takes optional serial port and baud rate arguments. The latter cannot be specified unless the former is as well. The serial port argument names a serial port device and defaults to /dev/ttyS0. The baud rate argument is an ASCII string describing a baud rate, and must be one of 50, 75, 110, 134, 150, 200, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400, 460800k, 500000, 576000, 921600, 1000000, 1152000, 1500000, 2000000, 2500000, 3000000, 3500000, or 4000000. It defaults to 19200. Particular software distributions may vary, but the default speeds for current motes platforms are as follows:
eyesIFXv2, intelmote2, telosb, tmote: 115200
mica2, micaz: 57600
