Chapter 4 Remote Interface ReferenceHalting an Output in ProgressHalting an Output in ProgressYou can send a device clear at any time to stop an output in progressover the GPIB interface. The status registers, the error queue, and allconfiguration states are left unchanged when a device clear message isreceived. Device clear performs the following actions:œ The function generator’s input and output buffers are cleared.œ The function generator is prepared to accept a new command string.œ The following statement shows how to send a device clear over theGPIB interface:CLEAR 710IEEE-488 Device Clearœ The following statement shows how to send a device clear over theGPIB interface using the GPIB Command Library for C or QuickBASIC:IOCLEAR (710)For RS-232 operation, sending the character will perform thesame operation as the IEEE-488 device clear message. The functiongenerator’s DTR (data terminal ready) handshake line is set “true”following a device clear message. See “DTR/DSR Handshake Protocol,”on page 198 for further details.216
