They do exactly what they're supposed to regardless of what sort of
bus is used to connect the CPU and the UART (ISA, PCI, PCI-express,
USB, Ethernet, etc.).

Sounds like you may be using this on a Windows machine. the code is
functional, it is best practice to close the port first before openiing it.
If due to an error, usually not syntax, the port will stay stuck open until
the program is closed and reopened. I have used the Python serial port

Hoi,
I'm trying to connect to a serial port and always get the error
"serial.serialutil.SerialException: Port is already open." whcih is untrue.
I have no serial port open yet, my code looks like this:
#!/usr/bin/python
import time
import serial
# configure the serial connections (the parameters
Turns out there's a windows package that works bautifully with
activestate python:
pyserial-2.4.win32.exe
Thank you.

http://switch.dl.sourceforge.net/sourceforge/pyserial/pyserial-2.4.tar.gz
to implement ymodem and other protocols on the PC com port
And it works like a charm in cygwin, but when I try to use it directly
in python under windows using active state python installat

PySerial has never been built in to any standard v

and the web page is the first hit
