This function reads the current state of the SRQ and NDAC lines of the specified GPIB board.

lBoard = 0xBB0000
Where:
BB = Board address (1 - 9)
This function returns a Long integer containing the status: Bit #0 (LSB) designates the state of SRQ line (1 for set, 0 for clear); Bit #1 designates the state of NDAC line.
A return value of -1 indicates that an error occurred during execution.
The following command reads the status of GPIB board #2 and determines if the SRQ line is asserted:
lStatus=GpibStatus(0x20000)
lSrqOn = lStatus <> -1 and (lStatus and 1)
