By the way, for future reference, this way beats the above hands down:
>>> import binascii
>>> binascii.unhexlify("D036EC")
'\xd06\x00\x00
Hello
ALSO... YOU NEVER SPECIFY A VARIABLE TO RECEIVE THE DATA -- ANYTHING
YOU DO READ IS BEING DUMPED ON THE FLOOR!
I see the read data with a sniffer.
with the same serial caracteristic in delphi i obtain the right answer.
I use serial writestr and serial readstr.
If the serial package is
Thanks for the info Grant. It'll teach me not to read the documentation

Well, I think it is better to start with some simple code first.
Try to read serial port and print it out.
something like this could work:
import serial
s = serial.Serial(port=2,baudrate=38400, timeout=20)
while 1:
print s.readline()

If you want help, you'll do better to post small pieces of code that you
are actually using, rather than making us guess or imagine what you are
doing. There are perhaps a dozen things

Anything's possible, but given that in his original post he says it
works when he uses Delph

Thanks for your help, but it don't solve the problem.
I receive only the echo and full stop.

Hello,
I'm not sure I understand precisely your question but maybe you can try
a readline and a flushinput like that:
import serial
port= 0 # or the port where you're device is connected
baudrate=9600 # or the baudrate of your device
s = serial.Serial(port, baudrate) # Open the port
for i in r
Thanks
