management.
The communication flow between the Host and NT600S differs according to the
following three cases:

The following describes control of the NT600S using the terminal commands.
For the actual procedure for using the terminal commands, refer to 7-4 Terminal
Commands (page 222).
The terminal commands allow the NT600S to be used as a terminal of the Host to
display text and graphics independently of the screens stored in the NT600S.
The Host sends a command and the NT600S processes the message. The
NT600S does not send back a response to the Host.
