+ Open given parallel port.
+
+ .. method:: setData(value)
+
+ Apply the given byte to the data pins of the parallel port.
+
+ .. method:: setDataStrobe(level)
+
+ Set the "data strobe" line to the given state.
+
+ .. method:: setAutoFeed(level)
+
+ Set "auto feed" line to given state.
+
+ .. method:: setInitOut(level)
+
+ Set "initialize" line to given state.
+
+ .. method: setSelect(level)
+
+ Set "select" line to given state.
+
+ .. method:getInError()
+
+ Set "Error" line to given state.
+
+ .. method:: getInSelected()
+

+
+ .. method:: getInAcknowledge()
+
+ Read level of "Acknowledge" line.

+
+.. module:: parallel.parallelutil
+
+.. class:: BitaccessMeta
+
+ This mix-in class adds a few properties that allow easier bit access to the
+ data lines. (D0 .. D7) e.g. p.D0 refers to the first bit of the data
+ lines.
+
+.. class:: VirtualParallelPort
+
+ This class provides a virtual parallel port implementation, useful
+ for tests and simulations without real hardware.
