menus are desired, the value entered would be 4 + 8 = 12.
Port Communication
The RS-232 can be set up in interactive or computer mode of communication. If the port is
attached to a computer running an instrument interface program, it needs to have different
characteristics than if used interactively by a human operator.
When an operator is communicating with the analyzer via a terminal, the analyzer should be
placed into TERMINAL MODE, which echoes keystrokes, allows editing of the command line
using the backspace and escape keys, and allows recall of the previous command. When a host
computer or data logger is connected to the analyzer, it should be placed into COMPUTER
MODE, which does not echo characters received or allow the special editing keys. See Table 6-
6-5 for relevant commands.
