Interactive Control (Usage Notes)
ibsre v
Input
| ud | Board descriptor |
| v | Indicates whether to set or clear the REN line |
Output
| Function Return | The value of Ibsta |
Description
If v is non-zero, the GPIB Remote Enable (REN) line is asserted. If v is zero, REN is unasserted. The previous value of REN is returned in Iberr.
REN is used by devices to choose between local and remote modes of operation. A device should not actually enter remote mode until it receives its listen address and REN is asserted.
