2.6.3.2 Using Sockets
The instruments allow up to six simultaneous socket connections to
be made.
ITECH instruments have SCPI socket services, which can be used to send and
receive SCPI commands, queries, and query responses. All commands must
be terminated with a newline for the message to be parsed. All query responses
will also be terminated with a newline.
