Sets manual control of the serial port's break state. If asserted, this property suspends character transmission and places the transmission line in a break state until this property is unasserted. If you want VISA to send a break signal after each write operation automatically, use the Break Length (Break Len) and End Mode for Writes (ASRL End Out) properties instead. The default is Unasserted.
