What Chris is getting at is that you'll use some module, eg pyserial, to
interface with the serial port. So if you write a little module that has
the same interface then you can pretend you have a serial port attached
device and then switch over to an actual one without changing anything
else in your code but the import.
## myserial.py ##
class Serial:
def __init__(self, port=None):
pass
def open(self):
pass
def close():
pass
def read(size=1):
return 'a' * size
def write(data):
return len(data)
#####
## foo.py ##
import myserial as serial
#import serial ## Use this in production
port = serial.Serial()
port.open()
print port.write("hello, world")
print port.read(3)
####
I hope that makes it clearer to you.
Adam.
P.S. none of that code has been tested

You don't need to emulate a serial port (since you're writing the code; you'd
have to emulate the port if it was standalone software), only your serial port
library. Write a class that has the same methods as the serial port library
you're using (you only need the methods you're using or think you might use
later), and fill them in with the appropriate code so it behaves like your real
device.

Hello list need some advice/help with something, i am doing a program
in python that send some command via serial to a device so far so good
, the thing is not have the program so i need make another program
that emulate the behavior of this serial device ( is quiet simple ) to
test my app
i read abou that i can use pseudo terminal in linux but not sure how
attatch the pseudo terminal /dev/pts5 example to a fake_device.py file
or something like that.
maybe this question is not so python but i will appreciate some help.
Thanks
