Introduction
This chapter describes the interface functions and some general
concepts of the RS-232C. The RS-232C interface on this instrument is
Agilent Technologies’ implementation of EIA Recommended Standard
RS-232C, "Interface Between Data Terminal Equipment and Data
Communications Equipment Employing Serial Binary Data
Interchange." With this interface, data is sent one bit at a time, and
characters are not synchronized with preceding or subsequent data
characters. Each character is sent as a complete entity without
relationship to other events.
