Table 5-11: RS-232 Switching From Terminal Mode to Computer Mode
Key Function
Control-T (ASCII 20 decimal) Switch to terminal mode (echo, edit)
Control-C (ASCII 3 decimal) Switch to computer mode (no echo, no edit)
If the command line doesn't seem to respond to keystrokes or commands, one of the first things
you should do is send a Control-T to switch the command line interface into terminal mode.
Also, some communication programs remove CTRL-T and CTRL-C characters from the byte
stream, therefore these characters will not be sent to the analyzer. Check your communications
program owners manual.
Entering Commands in Terminal Mode
In terminal mode, all commands must be terminated by a carriage return; commands are not
processed until a carriage return is entered. While entering a command you may use the editing
keys shown in Table 5-12.
Table 5-12: RS-232 Terminal Mode Editing Keys
Key Function
CR (carriage return) Execute command
BS (backspace) Backspace one character to the left
ESC (escape) Erase entire line
Commands are not case-sensitive; you should separate all command elements (i.e. keywords,
data values, etc.) by spaces.
Words such as T, SET, LIST, etc. are called keywords and are shown on the help screen in
uppercase, but they are not case-sensitive. You must type the entire keyword; abbreviations are
not accepted.
NOTE
To open the help screen,
Type "?" and press the Enter key.
