AllSPoll() causes the interface board specified by board_desc
to serial poll all the GPIB addresses specified in the addressList
array. The results of the serial polls are stored into resultList
.
If you only wish to serial poll a single device,
ReadStatusByte() or
ibrsp() may be
more convenient.
This function may also be invoked with the alternate capitalization 'AllSpoll' for compatibility with NI's library.
