Hi, I'm new to python and trying to learn serial communication using python.In this process i'm facing serial port issues.Please find the attached COMPorttest.py file ,correct me if anything wrong in the code.With my code it's always goes in to exception.I noted down the the COM port number from windows device manager list. Operating system: XPPython Ver: 2.5Pyserial: 2.5 Even i tried from python shell passing below commands import serialser=ser=serial.Serial(port=21,baudrate=9600) I observe below error on python shell File "C:\Python25\lib\serial\serialwin32.py", line 55, in open raise SerialException("could not open port: %s" % msg)SerialException: could not open port: (2, 'CreateFile', 'The system cannot find the file specified.') Thanks in advance. Best Regards,Chandan.
import serial def checkPort(): """ This function reads the serial port and writes it. """ try: ser = serial.Serial( port=21, baudrate=9600, bytesize=serial.EIGHTBITS, parity=serial.PARITY_NONE, stopbits=serial.STOPBITS_ONE, timeout=10 ) if ser.isOpen(): print "Port Open" else: ser.close() print"port closed" except serial.serialutil.SerialException: print "Failed to open port" checkPort()
