Description
If set to VI_STATE_ASSERTED, it suspends character transmission and places the transmission line in a break state until this attribute is reset to VI_STATE_UNASSERTED. This attribute lets you manually control the assertion state and length of a break signal. If you want VISA to send a break signal after each write operation automatically, use the VI_ATTR_ASRL_BREAK_LEN and VI_ATTR_ASRL_END_OUT attributes instead.
