I am able to open port COM4 with Terminal emulator.
So, what can cause PySerial to generate the following error ...
C:\Wattcher>python wattcher.py
Traceback (most recent call last):
File "wattcher.py", line 56, in <module>
ser.open()
File "C:\Python25\Lib\site-packages\serial\serialwin32.py", line 56, in
open
raise SerialException("could not open port %s: %s" % (self.portstr,
ctypes.WinError()))
serial.serialutil.SerialException: could not open port COM4: [Error 5]
Access is denied.
