See e.g. www.millisecond.com/forums/Topic1721.aspx for how this works in principle. For an elaborate example re. use of <port> elements, see the Auditory Oddball Task script available in the library.

Group: Forum Members Posts: 6, Visits: 13	Within a parametric n-back task, I'm trying to send a response marker out to the parallel port for correct responses (hitting the 'a' key at a target response). Currently I am getting stimulus markers specific to each level of n-back (1,2 or 3) and I've copied the part of my script specific to the parallel port below. Not sure how I should proceed to have a response marker coming out as well. <port EEGsignal> / port = lpt3 / subport = data / items = ("00000001", "00000011", "00000101") / select = values.N </port> <port EEGsignal2> / port = lpt3 / subport = data / items = ("00000010", "00000100", "00000110") /select = values.N </port> <port EEGsignaloff> / port = lpt3 / subport = data / items = ("00000000") </port> <block EndExp> / trials = [1 = EndExp_trial] </block>
