+**************************************************************************
+*  Mnemonic: SIterm
+*  Abstract: This routine will terminate a session based on the tp_blk
+*            that is passed into the routine. The transport session block
+*            is released and removed from the ginfo list. The session is
+*            terminated by issuing a t_unbind call (if the unbind flag is
+*            on in the tpptr block), and then issuing a t_close.
+*  Parms:    gptr - Pointer to the global information block
+*            tpptr - Pointer to tp block that defines the open fd.
+*  Returns:  Nothing.
+*  Date:     18 January 1995
