Comunicating through COM ports

[David Mallwitz]

FW: Comunicating through COM ports

    Ah, ok. Two possibilities here - 1) download a Python distro that has
the Serial package already incorporated (I know Activestate comes with it,
not sure about PythonWare) or 2) figure out how to make the Serial module
work with the plain vanilla Python install from python.org.
    Since 2.2 was just released I downloaded it from python.org and
installed, then copied the Serial package over to libs/site-packages. This
imports the Serial module just fine, but fails on the 'Serial.Serial'
function apparently because 'elapsedTimer' can't be found. I'm guessing that
it's just a PYTHONPATH issue, but I don't have time to work through it right
now. I'll post the Serial module if you want to try the second option, but
the fastest/easiest choice would be to download the Activestate distro
(www.activestate.com). On the other hand, I'm kind of down on Activestate
right now since the lastest release of their IDE 'Komodo' won't honor my
home-user license so maybe it's time to give PythonWare a try
(www.pythonware.com).

Best,
Dave

FW: Comunicating through COM portsWhich Python distribution are you using?
Or did you compile from source?

Sorry, but as I said before, I'm under windows98 and I haven't such
directory.
Do I need to download that module from anywhere?!If so, give me an URL.
