AR_INT_SET
CEI_INT16 ar_int_set (CEI_INT16 board, CEI_INT32 int_num);
This routine is only available for the CEI-220/420. It specifies the
interrupt number to be used by the board when interrupting the host. This
routine may be invoked while the interface is running.
To change the interrupt number used by the CEI-100/200 boards, you must
change the jumpers on the board.
The default interrupt, which is used by the CEI-220/420 if this routine has
not been called, is interrupt 5. The CEI-520/520A/620/820/820TX boards
are PCI/cPCI/PMC boards; the host computer BIOS or operating system
assigns the actual interrupt number used by the board.
ARS_NORMAL Success.
ARS_INVBOARD An un-initialized or invalid board was
selected.
ARS_INVARG An invalid channel was selected.
ARS_NO_HW_SUPRT Not a CEI-220/420, or invalid interrupt
number.
