The last line above is a hint to your problem.  The GreenSpring Octal232
module needs more register space than is normally available in the IPAC
module Register area, so it also needs the carrier to provide some memory
space for its interrupt vector register.  There are jumpers on the VIPC616
that set the A24 base address for the IPAC memory space (I strongly
suggest you do not use A32 space because that will need changes to your
vxWorks build).  You will also need to provide additional arguments in the
ipacAddCarrier initialization string to tell the carrier driver where and
how much memory you have set them up for - use the smallest 64KB setting,
and read the VIPC616 section of the drvIpac documentation for details.
