The "Instrument"
menu items are also represented by large buttons at the right side of the
NemaTalker window. It is up to the user to use either the menu or the
buttons to open an instrument.

Common to all instruments
Common to all instruments is
the box above. Here you can tell NemaTalker to calculate a checksum for
each sentence, and the interval in seconds that the sentences have to be
send to the selected communications port. So setting the value to 3 means
that every 3 seconds the selected sentences will be transmitted.
Setting the Transmit
Interval to 0 (zero) will fire a "single shot", each time you
click the start or continue button on the instrument.

Note that the user interface
of NemaTalker is based on the "Multiple Document Interface"
technology, which means that the instrument windows are treated as child
documents within the main window, and can be arranged at will within the
borders of the main window.
