The PPOLL CONFIGURE statement configures the parallel poll response for the specified remote IEEE-488 device(s). You specify either an I/O Path or a device selector that refers to one or more IEEE-488 devices and a parallel poll configuration value from zero through 15. The three least significant bits of its binary representation select the data bus line and the fourth bit selects the logical sense of the response. For example:
PPOLL CONFIGURE 702;3
configures device number two on interface number seven to respond on data line DIO4 with a logic sense of zero when its status bit is set.
If the computer is not the active controller or if only an interface select code is specified, an error is generated. The bus action is as follows: ATN, MTA, UNL, LAG, PPC, PPE.
