6.13.2.2. Help Commands in Terminal Mode
Table 6-26: 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
key.
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-C Pauses the listing of commands.
Control-P Restarts the listing of commands.
6.13.2.3. 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) that defines the type of command. Allowed
designators are listed in Table 6-27 and Appendix A-6.
[ID] is the analyzer identification number (Section 6.10.1.). Example: the Command
“? 200” 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 200.
COMMAND is the command designator: This string is the name of the command being
issued (LIST, ABORT, NAME, EXIT, etc.). Some commands may have additional
arguments that define how the command is to be executed. Press ? <CR> or
refer to Appendix A-6 for a list of available command designators.
<CR> is a carriage return. All commands must be terminated by a carriage return
(usually achieved by pressing the ENTER key on a computer).
