Description
VI_ATTR_SEND_END_EN specifies whether to assert END during the transfer of the last byte of the buffer.
VI_ATTR_SEND_END_EN is relevant only in viWrite and related operations.
On Serial INSTR sessions, if this attribute is set to VI_FALSE, the write will transmit the exact contents of the user buffer, without modifying it and without appending anything to the data being written. If this attribute is set to VI_TRUE, VISA will perform the behavior described in VI_ATTR_ASRL_END_OUT.
On GPIB, VXI, GPIB-VXI, TCP/IP INSTR, and USB INSTR sessions, if this attribute is set to VI_TRUE, VISA will include the 488.2 defined "end of message" terminator.
