# additional reference assembly mscorlib to have all data
types
# available that are used by SerialPort
clr.AddReference("mscorlib")
Open the COM Port
# create an instance of SerialPort for COM4
serialPort = System.IO.Ports.SerialPort("COM4")
# configure COM4 to 9600 bit/s 8N1
serialPort.BaudRate = int (9600)
serialPort.DataBits = int(8)
# available choices for Parity are
# None: System.IO.Ports.Parity.None
# Odd : System.IO.Ports.Parity.Odd
# Even : System.IO.Ports.Parity.Even
# Mark : System.IO.Ports.Parity.Mark
# Space : System.IO.Ports.Parity.Space
serialPort.Parity = System.IO.Ports.Parity.None
# available choices for StopBits are
# None : System.IO.Ports.StopBits.None
# One : System.IO.Ports.StopBits.One
# Two : System.IO.Ports.StopBits.Two
# OnePointFive : System.IO.Ports.StopBits.OnePointFive
serialPort.StopBits = System.IO.Ports.StopBits.One
# set read and write timeouts to 500ms
serialPort.ReadTimeout = int(500)
serialPort.WriteTimeout = int(500)
# finally open the COM port
serialPort.Open()
Reading and Writing Data
# write a string
serialPort.Write("Sending string data")
# sending binary data
# prepare the data to be sent. SerialPort expects an Array
of Byte. This requires importing mscorlib!
