Serial

serial:streamer(Charstring serial_port,Integer baud_rate,Integer start_byte,
               Integer stop_byte,Integer data_len)->Stream of Binary

Get a stream of binary from a serial port named serial_port. The streamer works by looking for start_byte in the serial stream, when it finds a start_byte it will look data_len+1 bytes ahead to check if it is a stop_byte. If this is the case the data_len bytes between start_byte and `stop_byte is emitted.

Example binary stream for serial:sreamer("COM8",115200,0x55,0xAA,8):

Start byte                               Stop byte
|                                            |
0x55 0x01 0x02 0x03 0x04 0x05 0x06 0x07 0x08 0xAA
|                                  |
|---------- 8 bytes of data -------|

You can use unpack to get individual numbers from the binary object.
