Beginner Pyserial Question

[JAMoore84]

Hi Guys,

I have a project where I'd like to save GPS data that is streamed to a
Sony Vaio over bluetooth. I can monitor the data stream over Hyper
Terminal, but I'd like to use python to capture it as well. I've
installed Python 2.5, pyserial 2.2 and the appropriate pywin program
(pywin32-210.win32-py2.5.exe).

My problem comes when I try to open a serial port. After importing
"serial", I issue the following statement:

>>GPS = serial.Serial(0)

Traceback (most recent call last):
File "<pyshell#3>", line 1, in <module>
GPS = serial.Serial(0)
File "C:\Python25\lib\site-packages\serial\serialutil.py", line 156,
in __init__
self.open()
File "C:\Python25\lib\site-packages\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.')

I'm not sure where the source of the problem is. I was wondering if
someone could recognize what might be be. the Vaio is running XP
SP2. Thanks!

I've solved the problem- Thanks for steering me in the right
direction.

The problem is that your traditional "COM1" does not exist on this
computer (Thanks Grant). A trip to the Device manager listed all the
COM ports on the computer. After successfully connecting to COM7 (port
= serial.Serial(6)), I realized the reason I couldn't connect to COM40
was because it was tied up with hyper terminal. after closing
everything, I was able to issue a readline and collect data. Thanks
for the help!
