ibrpp Performs a parallel polling.
ibrsp Performs a sequential polling.
ibsad Sets or disables a device secondary GPIB address.
ibstop Stops the asynchronous I/O operation.
ibtmo Sets the board or device timeout period.
ibtrg Sends the Group Execute Trigger (GET) message to device.
ibwait Monitors event(s) until one or more events that are described by mask or
delay operating occur.
ibwrt Writes data from a buffer to a device.
ibwrta Writes data from a buffer to a device asynchronously.
ibwrtf Writes data from a file to a device.
