NAME

iclear − SICL utility for clearing interfaces or devices

SYNOPSIS

iclear [-t timeout] [-v] [-?] <sym_name>

DESCRIPTION

Iclear performs a device or interface defined clear operation on the device or interface specified by the sym_name parameter.  Sym_name is the SICL address of the device or interface being addressed.  If sym_name refers to a device, then a device clear command will be sent to the device.  If sym_name refers to an interface, the interface clear command will be sent to that interface.  The actual functions of the device clear or interface clear are specific to the device or interface. 

For example, executing iclear on an HP-IB device will result in the DCL command being sent to that device.  Executing iclear on an HP-IB interface will result in the IFC line being pulsed (if the interface is system controller), and the interface hardware being reset. 

The iclear command, when used on a VXI interface session causes a pulse on the SYSRESET line which cancels the normal operation state until the resource manager has reconfigured the VXI system.  The iclear command, when used on a VXI message-based device session sends a word-serial device clear command to the specified device. 

The parameter definitions follow. 

t <timeout>
Times out after timeout milliseconds.

v Turns on verbose mode. 

?  Prints the usage of the iclear program.
