Using National Instruments VISA
If you are using National Instruments VISA, be sure to set the following variables as follows:
VI_ATTR_SEND_END = VI_FALSE ‘ This specifies whether to assert END during the transfer of the last byte of the buffer
VI_ATTR_TERMCHAR = 0x0A ‘ This is the termination character. When the termination character is read and VI_ATTR_TERMCHAR_EN is enabled during a read operation, the read operation terminates.
VI_ATTR_TERMCHAR_EN = VI_TRUE ‘ This is a flag that determines whether the read operation should terminate when a termination character is received.
VI_ATTR_SUPPRESS_END_EN = VI_FALSE ‘ Specifies whether to suppress the END bit termination. If this attribute is set to VI_TRUE, the END bit does not terminate read operations. If this attribute is set to VI_FALSE, the END bit terminates read operations.
