pyserial script doesnt execute properly

[kishore]

hello there

Iam using python 2.5.4
pyserial  2.4
pywin32-214

on windows 7


i hav a small test script written to query a serial device (arduino)
and get back reply appropriately



////file: test.py

import serial
print 'hi'
ser=serial.Serial(port='\\.\COM2', baudrate=9600)
ser.close()
ser.open()
ser.write('1')
ser.readline()
ser.readline()
ser.close()



the device waits for '1' through its serial interface and print two
lines if it gets '1'

"Some Data found" and "Header received"


the script works on IDLE well when given one line at a time

but when given in command line as python test.py it prints hi and wait
forever

can anyone help?
thanks in advance
