Hi,
I thought it is best to post this question as a separate topic. Our ISCAN tracker can send a bunch of eye-data parameters via serial port and although I am able to open a serial port on my ML experimental PC and read in and parse this data in the experiment matlab script. It will be great if I can write a matlab function/hook that can help ML directly read eye data from serial port, unpack it and use the x,y signal. The advantage of such a function is that we can experiment with different possibilities (pupil x,y or pupil-CR xy). Is this possible in ML ?

best,
Harish

You can't keep monitoring serial ports all the time at the script level. NIMH ML supports TCP/IP, so try it instead if you are interested in digital signal transfer.
