> Outline:
> 
> The Open Instrumentation Project (OIP) makes low cost measurement
> equipment -- hardware and Open Source Software -- available to engineers,
> hobbiests and students.
> 
> First, we describe programming in the Tcl/Tk language with special
> emphasis on rapid creation of a graphical user interface. We show it has
> been used in the OIP, and how its capabilities can be applied to other
> instrument and control projects.
> 
> We then provide some background on methods of interfacing to the PC and
> the functions of the legacy serial, printer and bus ports. The USB port is
> rapidly replacing these methods, and so we explain the advantages and
> challenges of using USB. We describe the hardware and software of a simple
> approach to the USB interface, and provide pointers to some USB debugging
> tools. This will be of interest to anyone building hardware that talks to a
> the USB interface.
> 
> We will demonstrate Tcl/Tk and the USB interface with a 20MSample/second
> dual channel oscilloscope, and a 100kHz arbitrary waveform generator. We
> will show how these instruments can be operated together by an open-source
> program to form a vector network analyser.
> 
> As our contribution to Command Line 101, we'll open with some basic tricks
> for moving around between Linux directories and executing commands with a
> minimum of keystrokes.
