11.1
Terminator
Host can send a string of command to instrument, instrument terminator will begin parsing after
it captures end mark
(

)
or after input buffer overflows.

performing command string only after it receives end mark or after
buffer overflows.

If command handshake is turned on, every time terminator receives one string, it will promptly
return this string to the host, only when host receives this returned string, can it continues sending
the next string.

．
After terminator parses error, it will promptly stop parsing, and the current command is canceled.
5

When terminator parses the query command, it will terminate parsing this command string, the
latter command string will be ignored.
