[solved] dportio.dll

  If the first script doesn't run, this could be due to some unexpected indent. The correct syntax is as follows:

  try:
      from ctypes import windll
      global io
      io = windll.dlportio # requires dlportio.dll !!!
  except:
      print 'The parallel port couldn\'t be opened'
  

  Further potential issues:

  1. Have you installed the correct version of dlportio? For more information, see here, and have a look at this thread for instructions on how to install it on Windows 7.

  2. If I understand correctly, you're trying to access a emulated parallel port? If not, and you're trying to access the ethernet port, have a look at Python's socket module. You can find a nice code example here.

  Good luck!

  Okay , thanks actually i solve the problem may be few hints may cause problem but
  now it work
  the problem in this line for understanding
  global io
  trigger = 1
  port = 1024

  here the port , actually the TCP client port is 1024 , so when i am writing the same port there is n't any connection

  so i am trying data stream bridge but also it can't read

  how can i link between TCP client port and dportio.dll?

  how can i add TCP communication to python like pyserial communication

  I'm afraid I don't really understand the question. I think the problem boils down to this: Either use dlportio.dll for parallel port communication, or use the socket module for ethernet communication. Don't try to use dlportio.dll for ethernet communication.

  In the example that I link to, the port number is defined in the variable TCP_PORT. Change that to whatever port number you need, and change the IP address to whatever IP you need.

  If you can't read what's coming back other the TCP connection, then just use the send method, not the recv.

  Good luck!

  Thanks Edwin , Finally i made communication between opensesame and TCP client
  via this

  import socket
  import sys
  
  
  #create TCP/IP socket
  sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
  
  
  #connect socket to the port 
  server_address = ('localhost', 10000)
  print >>sys.stderr, 'connecting to %s port %s' % server_address
  sock.connect(server_address)
  

  Now it receive communication thanks Edwin
  but i have a question about EEG channel location do u can help me in this

  Good that you got it working!

  The last actual research I did with EEG was using Matlab and an obscure setup, and it was years ago. I have done a lot of teaching on the basics of the subject, but I am certainly no expert in the methods. So I'm afraid you'll have to look for help on the channel location elsewhere, e.g. with the company that provides you with the analysis software, of a colleague in the field.

  Good luck!

  so , if i am asking about the physiology , i supposed simulate UAV operator stress
  so how can i make this experiment in opensesame

  Another question i need software for creating eeg montages i see CSD but it contains bugs , could u recommend me
