 ===== Instrument communication =====
-Python IVI can use Python VXI11, pySerial and linux-gpib to connect to instruments. The implementation of the initialize method takes a VISA resource string and attempts to connect to an instrument. If the resource string starts with TCPIP, then Python IVI will attempt to use Python VXI11. If it starts with GPIB, it will attempt to use linux-gpib's python interface. If it starts with ASRL, it attemps to use pySerial. Integration with PyVISA is planned, but not currently supported.

 ===== Usage example =====
-This sample Python code will use Python IVI connect to an Agilent MSO7104A over LXI (VXI11), configure the timebase, trigger, and channel 1, capture a waveform, and read it out of the instrument.
