| Note: The DeskPorte FAST modem can be configured by |
| switches in eleven modes, although command |
| configuration is preferable when possible. |
| Configuration modes 1 through 9 can be stored in |
| NVRAM by pressing the reset switch. Mode 0 is read on |
| reset or power-up is SW2/5 is on. If SW2/5 is off, no |
| switch settings will be used. Before operating, the |
| modem’s switches should be returned to mode 0 and the |
| appropriate settings made. |
