A binary mask determining which pins on a parallel port an input device should use.
<likert> <openended> <surveypage> <trial>
For each pin, a value of 0 indicates that any input device connected to the port should not change the state of the corresponding pin. A value of 1 indicates the input device can change the corresponding pin. This is useful in cases where different pins on a parallel port are being used simultaneously for input and output. By restricting the pins affected by the input device, the input will not interfere with output signals.
The following displays the value of inputmask in a text stimulus:
/ items= ("inputmask = <% trial.foo.inputmask %>")
The following displays the value of inputmask in an instruction page:
inputmask = <% trial.sometrial.inputmask %>
