8.2. INTERACTIVE MODE

Interactive mode is used with a terminal emulation program such as

HyperTerminal or a “dumb” computer terminal.

8.2.1.1. HELP COMMANDS IN INTERACTIVE MODE

Table 8-1: Terminal Mode Software Commands
COMMAND Function
Control-T Switches the analyzer to terminal mode
(echo, edit). If mode flags 1 & 2 are OFF,
the interface can be used in interactive
mode with a terminal emulation program.
Control-C Switches the analyzer to computer mode
(no echo, no edit).
CR
(carriage return)
A carriage return is required after each
command line is typed into the
terminal/computer. The command will not
be sent to the analyzer to be executed until
this is done. On personal computers, this is
achieved by pressing the ENTER button.
BS
(backspace)
Erases one character to the left of the
cursor location.
ESC
(escape)
Erases the entire command line.
?[ID] CR This command prints a complete list of
available commands along with the
definitions of their functionality to the display
device of the terminal or computer being
used. The ID number of the analyzer is
only necessary if multiple analyzers are on
the same communications line, such as the
multi-drop setup.
Control-P Restarts the listing of commands.

8.2.1.2. COMMAND SYNTAX

Commands are not case-sensitive, and all arguments within one command (i.e.

ID numbers, keywords, data values, etc.) must be separated with a space

character.

All Commands follow the syntax:

X [ID] COMMAND <CR>
Where
X is the command type (one letter; refer to Table 8-2) that defines the type of
command. Allowed designators are listed in Appendix A-6.
[ID] is the machine identification number (Section 6.2.4). Example: the
Command “? 803” followed by a carriage return would print the list of
available commands for the revision of software currently installed in
the instrument assigned ID Number 803.
