/*
 * Commands sent to the shared memory programs:
 * Source:
 * pnet->prun->psrv..
 * bpCmd -> bpInp,bpOut
 *
 * When sent thru the shared memory nodes:
 * 1. short nosed used (data limited to 4k)
 * 2. the command goes in node.subType field.
 *    the node.type is set to BP_NDTYPE_CMD=3 (see bufpool.h)
 * 3. There is a msgId in the node. bpCmd sets it. Replys will have the
 *    same number. this is how bpCmd recognizes where the reply comes
 *    from.
*
* -----------------------------------------------------------------------------
* BPCMD_CMD_FILE - file command
* -----------------------------------------------------------------------------
*	External user -> bpCmd .. goes to bpOut.. but put on bpInp queue
*   F type (fits,pdev) - type of file
*                        This will deselect the other file type
*                        Should do this before data recording (pnet)
*                      - reply ok: or err:
*   				     passed back in pnode.data
* -----------------------------------------------------------------------------
* BPCMD_CMD_DBG - debug command. Programs send back ascii data about themselves
* -----------------------------------------------------------------------------
*
*       External user -> bpCmd, or bpInp,bpOut via bpCmd.
*       externalUser->bpCmd
*         	D prgnam     .. bpinp,bpout,bpcmd
*       bpCmd-> external user
*         	"ok:"    or  "err:"
*        	 Followed by the ascii debug info.. limited to 4k
*
*       bpCmd-> nodes
*        	node.subtype="D" *             	data    none
*       nodes -> bpCmd
*		note.pdata holds the ascii info. 
*               node.blksize holds how long it is.
* -----------------------------------------------------------------------------
* BPCMD_CMD_NOP - nop command.
* -----------------------------------------------------------------------------
*       External user -> bpCmd, or bpInp,bpOut via bpCmd.
*       externalUser->bpCmd
*         N prgnam     .. bpinp,bpout,bpcmd
*       reply bpCmd-> external user
*         "ok:"    or  "err:"
*       bpCmd-> nodes
*        node.subtype="N"
*             data    none
* -----------------------------------------------------------------------------
* BPCMD_CMD_SETP - SETP command from pnetctl to bpOut
* -----------------------------------------------------------------------------
*       External user -> bpCmd, or bpInp,bpOut via bpCmd.
*       externalUser->bpCmd
*         N prgnam     .. bpinp,bpout,bpcmd
*       reply bpCmd-> external user
*         "ok:"    or  "err:"
*       bpCmd-> nodes
*        node.subtype="N"
*             data    none

* -----------------------------------------------------------------------------
* BPCMD_CMD_SHM- shm info command.
* -----------------------------------------------------------------------------
*       External user -> bpCmd,
*         S    
*       reply bpCmd-> external user
*         "ok:"    or  "err:"
*       followed by ascii data showing the current queue usage
*               
* -----------------------------------------------------------------------------
* PSRV_CMD_OPENFILE sent psrv to bpInp,bpOut.   
* -----------------------------------------------------------------------------
* 		u32 - first seq number to use
*       u32 - nblocks to write before done with run
*       u32 - maxFilesize in Kb before switching to next file.0--> no switch
*+      u32 - number of blocks per pnode we will be using. Each block 
*             is an accumulated output from pdev.
*              The last may dump may be different.
*     string- /dir/fname up to sequence number (without.). null terminated
*     Notes: this command comes from pnet. psrv passes it along in the
*            the msg queues to bpInp then bpOut. 
*    08may08  .. tried switching to 4 bytes by pnode only has 1 byte for subtype.
*                goback to 1 byte
