7.1.7. TERMINAL OPERATING MODES 
The T703 can be remotely configured, calibrated or queried for stored data through the serial ports.  As 
terminals and computers use different communication schemes, the calibrator supports two communicate modes 
specifically designed to interface with these two types of devices. 
  Computer mode is used when the calibrator is connected to a computer with a dedicated interface 
program.  
  Interactive mode is used with a terminal emulation programs such as HyperTerminal or a “dumb” 
computer terminal.  The commands that are used to operate the calibrator in this mode are listed in Table 
7-2. 
7.1.7.1. Help Commands in Terminal Mode 
Table 7-2:  Terminal Mode Software Commands 
COMMAND Function 
Control-T 
Switches the calibrator 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 calibrator 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 calibrator 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 
calibrator is only necessary if multiple 
calibrators 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.
