IBWRT and Send are almost the same, but the difference is
IBWRT does not send CR nor LF characters unless the text
contains the terminater chars at the last. But Send function
can control LF or LF+EOI when it is called. If the instrument
can accept several kinds of term chars, the behaviour is exactly
the same. In other words, IBWRT can be used for both 488.1/.2
devices and also true for Send() function.
