9 LIST OF DEVICE CONTROL INSTRUCTIONS

Device control instructions are used to determine the communication sequence between the PNC-900 and computer through RS-232C interface and to tell the computer the current PNC-900 state. Among them, some device control instructions set the output specifications of CAMM-GL III instructions.

Each device control instruction is organized with three letters: [ESC] , "." and one uppercase letter. Device control instruc-

tions are of two types: one with parameters and the other without parameters.

Parameters can be omitted. A semicolon ";" is used as a delimiter to separate parameters if they are input in succession. A ";" without parameters means that parameters were omitted.

If parameters are omitted, the default value is set. For a device control instruction with para-meters, a terminator needs to be input in order to signify the end of instructions. A colon ":" is used as the terminator which cannot be omitted.
