- The 1740, 1740A and 1742 have two modes of operation, 'Standard Mode' which
- is directly compatible with the 1540-series, and 'Enhanced Mode' which offers

- Reference, page 1-2):

- Of these, only 'single fast mailbox handling' differs from a software
- point of view from the 1540-series. While they are different, they
- are not 'completely new'.
