a) USBTMC:

/* to an USB Test & Measurement Class (USBTMC) instrument using
/* NI-VISA
/* The example writes the "*IDN?\n" string to all the USBTMC */
/* devices connected to the system and attempts to read back
/* results using the write and read functions.
/* The general flow of the code is */
/* Open Resource Manager
/* Open VISA Session to an Instrument
/* Write the Identification Query Using viPrintf
/* Try to Read a Response With viScanf
/* Close the VISA Session
