You set up <port> elements and "display" them like you would with any other kind of stimulus element (<text>, <picture>, etc.), i.e. add them to the various <trial> element's /stimulusframes or /stimulustimes attributes. This is script is a good example:

https://www.millisecond.com/download/library/oddball/

Thank you, I have tried to follow the inquisit script but I am getting error messages

<port attributeA>
/ port = LPT1
/ subport = data
/ items = ("00000001")
</port>

<port attributeB>
/ port = LPT1
/ subport = data
/ items = ("00000010")
</port>

<port targetA>
/ port = LPT1
/ subport = data
/ items = ("00000011")
</port>

<port targetB>
/ items = ("00000001")
/ port = LPT1
/ subport = control
/ erase = false
</port>

I am also lost, in the sense that I don't have an idea of how to go about defining the port items for the two attributes and two targets

I can't say anything about error messages without knowing what exactly those error messages are. If they tell you that the port you specified cannot be found, adjust the port number accordingly, e.g. LPT2 instead of LPT1. You can test communication with your equipment via the port monitor: https://www.millisecond.com/support/docs/v4/html/howto/howtoportmonitor.htm

Also see for more background: https://www.millisecond.com/support/docs/v4/html/howto/howtosendport.htm

> I am also lost, in the sense that I don't have an idea of how to go about defining the port items for the two attributes and two targets

Like any other stimulus element, <port> elements may have several items. You can pair different TTL signals to the different items in your attribute and target stimuli.
See https://www.millisecond.com/support/docs/v4/html/howto/howtopairs.htm

Pairing a port stimulus' items to a <text> element's items works the same way as pairing two <text> elements.

Finally, your <port> elements *must* have unique names. Elements of the same *class* may not have identical names. I.e., you cannot have

<text attributeA>
...
</text>

and

<port attributeA>
...
</port>

in the same script. A <trial> like

<trial example>
/ stimulusframes = [1=attributeA]
...
</trial>

will have no way of knowing whether you want it to display the <text> element or the <port> element. You need to have something like

<text attributeA>
...
</text>

and

<port attributeAsignal>
...
</port>

with 

<trial example>
/ stimulusframes = [1=attributeA, attributeAsignal]
...
</trial>

Thank you, I will try the code today.

Ok, I followed the advise from the forum, and it worked. Thank you so much. However now I have another problem. How do I go about sending a TTL trigger for a survey using inquisit . Survey has radio buttons instead of item, how do i define the port signal for each question. In which section should i insert the codes for sending triggers for each question and how?Any form of assistance will be greatly appreciated.

> Survey has radio buttons instead of item, how do i define the port signal for each question.

What do you mean by "port signal for each question"?

If you want to send a TTL trigger indicating the start of a given <surveypage>, you can do so via the page's /stimulusframes just like you do in regular <trial> elements. I.e.

<surveypage siyazama1>
/ stimulusframes = [1=s1_ttl]
...
</surveypage>

with

<port s1_ttl>
...
</port>

and so forth.

ok, I will try that, thank you very much

 "port signal for each question" - I have set up my survey such that each page only contains one question, in hope that a trigger will be sent out for each question.

Then the approach outlined in my previous response should work.
