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)

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)

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.
