PySerial

I'm using pySerial to connect to a serial port (rs232) on a windows xp
machine. I'm using python interactive interpretor to interact with the
device. I type the following:
import serial
ser = serial.Serial(2)
ser.write("command")
But this does nothing to the control. I have been able to connect via puTTY
to verify that the command and the device are working. Next I tried to open
the port before
writing. It looks like this:
import serial
ser = serial.Serial(2)
ser.open()
It returns that an error. It states that I do not have permissions? I don't
know how to resolve either issue. Any help would be greatly appreciated.

Have you tried setting the baud rate? (the `baudrate` param to
Serial's constructor)
Why are you using port #2 and not #0?
Cheers,
Chris

I have tried setting the baud rate with no success. Also I'm using port #2
because I"m using a usb to serial cable.

Note that Serial(2) is known as COM3 in Windows, is it ok?

Yes, with the serial to usb adapter is located on COM3. I have been able to
use puTTY to get into the port and shoot commands at the device, but when I
try to use python I get 'You don't have permissions".
