e prime and emotiv neuroheadset

[juan concepcion]

Hello again! I've tried sending markers from e-prime to the emotiv 
testbench application <http://www.emotiv.com/eeg/test_bench.php> for when a 
stimulus is presented on the same computer but have not had any luck. Now I 
would like to use a stimulus presenting computer using e prime and sending 
the markers to a parallel port to testbench on another computer. How can I 
connect two computers through a parallel ports to use e-prime on one 
computer and testbench on another?
