Communications Using RS-232C (NT20-ST128)
This section gives a brief description of the NT20 control commands sent from
the host through the RS-232C interface when the NT20-ST128 is used.
For details on each of the commands sent through the RS-232C interface,
refer to
SECTION 6 Using RS-232C Communications
.
Control of the NT20 by a Host is executed by two kinds of commands sup-
ported by the RS-232C interface that is built into the NT20.
Operation Commands
Operation commands are used to control the display and status of the running
NT20 as well as to provide notification.
They are used for purposes such as screen display, data writing, and enqui-
ries.
Notification of the NT20 operation contents can be provided to the Host.
Terminal Commands
Terminal commands are used to use the NT20 as a display terminal of the
Host.
When the NT20 is used as a display terminal, it can display characters and
figures according to instructions given by the Host, independently of the
screens registered to the NT20.
These commands are also used if unexpected problems occur.
