Command termination
The carriage return (cr), line feed (lf), semicolon ( ; ), or EOI sent concurrent with the last character indicate the end of message (command terminator) to the multimeter. When you send a command from the system controller in the standard format (e.g., OUTPUT 722;“TEST”), the controller typically adds a cr lf to the end of the command. With its input buffer off (off is the power-on input buffer mode), the multimeter processes the cr immediately, but does not process the lf until the command completes execution. This means that, because of the lf, the bus is held and you cannot regain use of the controller until the multimeter is done executing the command (or the GPIB CLEAR command is executed which aborts execution of the command). You can prevent. the bus from being held by suppressing the cr lf when sending commands or by enabling the input buffer (INBUF ON command). The following program line shows how to use the # and K image specifiers to suppress cr lf when sending a multimeter command.
OUTPUT 722 USING "#,K";"TEST;"
