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 modems switches should be returned to mode 0 and the appropriate settings made. | |
