6.0 TERMINAL PROGRAMMING
The Esprit terminal can be operated in many modes to assist the user in communicating with a com-
puter. Careful study and experimentation with those modes will familiarize the operator with the many
powerful communication techniques offered by the terminal.
6.1 Operating Modes
6.1.1 NORMAL Mode
When set to the NORMAL mode, the Esprit may be used as an interactive terminal to interact with the
computer in either FULL or HALF duplex communication mode.
6.1.2 MONITOR Mode
When the Esprit is set to the MON ITOR mode, all ASCII codes, including control codes, received by
the terminal will be displayed rather than being acted upon. Only the CR code (00 HEX) will perform
the Carriage Return function in addition to being displayed as a control code.
6.1.3 BLOCK Mode
When the Esprit is set to the BLOCK mode data will not be transmitted until the operator depresses
the "ENTER" key with or without [SH 1FT]. This function provides the operator with the ability to
edit data before it is transmitted. When the terminal is in this mode, it can exit to NORMAL mode only.
This mode is not available when either the Regent 25 or ADM-3A is being emulated.
6.1.4 LOCAL Mode
When the Esprit is set to the LOCAL mode, data entered at the keyboard is displayed but not transmitted.
Data received at the communication interface is ignored. Utilizing this operation mode the operator
can become familiar with the response to remote commands offered by the terminal. LOCAL mode
also allows the operator to prepare and edit a full screen display with the assurance that the host com-
puter will be unable to destroy the prepared text. When the terminal is in this mode, it can exit to
NORMAL mode only.
