im trying to read data on a COM port using python and the COM port allows me to access only one application at a time..

example: if i configure the putty or hyper terminal then i can read the tag data on the putty/hyperterminal console but when i try and run the python code ,then it shows me an error

as u see in pyserial image that i have attached below..it says "access denied'

later if i first run the python code, the code runs without error .. but the configure for putty/hyperterminl doesnt happen.. it say "unable to open the COM port" in putty/hyperterminal
