DEL DLL 2.0  :
  * Support for DEL-350 (PCI version of DEL-150) modules added
      - changes in .ini file, DELdata structure, del_def.h, functions set
  * Set of functions DELstd_.. is added for using in Visual Basic 
        with _stdcall calling convention.
       The only difference beetween these functions and original set of functions
          is calling convention.
  * Modules on the same PCI bus are ordered using serial number
    M0 - lowest serial number, M3 - highest serial number

DEL DLL 1.2  :
  * fields of DELdata structure are reordered to avoid padding of the data when
           using in Visual Basic or Pascal
