read and write in a serial port with python

[Charlotte1]

How can I read and write a radio connected to the computer with a serial port with python, the same way a hyperterminal does ?
I wrote this:

from Tkinter import *
import serial
se = serial.Serial()
se.baudrate = 9600
se.bytesize = 8
se.parities = 0
se.stopbits = 1
se.xonxoff = 0
se.rtscts = 0
se.timeout = 1
se.port = 0
print se.portstr
print se
se.close()

It seems to work, but when I try to communicate using
se.write('at')
se.readl([20])

I don't receive the expected answer, and it just reads what I wrote.

Someone can help me?

Hi Charlotte1,
I have the same problem! Have you resolved it?

Hi

I've used pySerial successfully in the past, though not with a radio. I found it to work pretty well in general, or at least the python part! Can you give us some more details? For example, what was the print out from the first bit of code you gave? Is there a particular reason for the parameters you choose there? Can you give us the exact print out for the second piece of code, and what you were expecting?
