Someone just asked me how to display the received bytes from two serial ports in different colours, from a Python script. I'm assuming they're using Windows, which means they want to use the WConio library to change the colour and the PySerial library to talk to the serial port.
So, here we go. Note that I use sys.stdout.write rather than print because I don't want to have either a space (as with print "foo",) or a carriage return (print "foo") after each bit of output.
done = 0
while not done:
for portname, port, colour in ports:
n = port.inWaiting()
if n:
WConio.textattr(colour)
sys.stdout.write(port.read(n))
while WConio.kbhit():
if WConio.getch()[0] == 27:
done = 1
