| IbcRsv | Sets the serial poll status byte of the board. | |
This option is used to request service from the Controller and to provide the Controller with an application-dependent status byte when the Controller serial polls the GPIB interface.
The value v is the status byte that the GPIB interface returns when serial polled by the Controller-In-Charge. If bit 6 (hex 40) is set in v, the GPIB interface requests service from the Controller by asserting the GPIB SRQ line. When IbcRsv is called and an error does not occur, the previous status byte is returned in Iberr.
