I"m trying to use pyserial. When I do the following script.

import serial
ser= serial.serial("COM5", 9600)
ser.write("Hello worldn")
x = ser.readline()
print(x)     

Error code:

c:\Python27>python com.py
Traceback (most recent call last):
  File "com.py", line 2, in <module>
    ser= serial.serial("COM5", 9600)
AttributeError: 'module' object has no attribute 'serial'

I read a suggestion and changed it to:

from serial import serial
ser= serial.serial("COM5", 9600)
ser.write("Hello worldn
x = ser.readline()
print(x)     

I now get the error

c:\Python27>python com.py
Traceback (most recent call last):
  File "com.py", line 1, in <module>
    from serial import serial
ImportError: cannot import name serial

I read that this can be from having ini in your module, but dont' know anyting about this.

I printed my sys.path and pyserial is in there.

['C:\\Users\\Jeff\\Desktop', 'C:\\Python27\\lib\\site-packages\\distribute-0.6.4
9-py2.7.egg', 'C:\\Python27\\lib\\site-packages\\pyserial-2.7-py2.7.egg', 'C:\\W
indows\\SYSTEM32\\python27.zip', 'C:\\Python27\\DLLs', 'C:\\Python27\\lib', 'C:\
\Python27\\lib\\plat-win', 'C:\\Python27\\lib\\lib-tk', 'C:\\Python27', 'C:\\Pyt
hon27\\lib\\site-packages', 'C:\\Python27\\lib\\site-packages\\setuptools-0.6c11
-py2.7.egg-info']

Getting kind of annoyed :(... Thanks for help.

It should be:

import serial
ser = serial.Serial("COM5", 9600)

Note the capital 'S' in serial.Serial
