*
* PURPOSE: This function sends the PCCC Identify Host and Some Status
* command to the PLC-5/40V.
*
* INPUT: ULONG vmeCmdBlkAddr contains the VME address where the
* command block will be copied to so the PLC-5/40V can
* access its information.
*
* UWORD baseAddress contains the base address of the
* PLC-5/40V.
*
* VME_DATA_WIDTH_TYPE width contains the data width that
* should be used for the copy operations. It can be D16
* or D08.
*
* VME_ADDRESS_MODIFIER_TYPE addrMod defines the address space
* in which the VME data is accessed. It can be A16 or A24.
*
* PLC540V_PCCC_IHAS_RPY_TYPE reply contains PCCC’s Identify
* Host and Some Status command specific reply packet.
*
* OUTPUT: PLC540V_STATUS_TYPE *status will contain the final status
* of requesting this function. This status could be and EPC
* or PLC-5/40V value.
