Configuring the Modem

SW3-2 Data Rate (Fast-Poll Mode Only)

SW3-2 ON = 4800 bps

OFF = 9600 bps

SW3-2 configures the modem speed. When the modem is in high- speed fast-poll mode (SW3-1 OFF), setting SW3-2 ON selects 4800 bps, while setting SW3-2 OFF selects 9600 bps.

SW3-3 Async Character (Fast-Poll Mode Only)

SW3-3 ON = 11 bits

OFF = 10 bits

Switch SW3-3 selects whether the async character is 10 or 11 bits long. When the modem is in high-speed fast-poll mode (SW3-1 OFF), setting SW3-3 ON selects an 11-bit async characters, while setting SW3-3 OFF selects a 10-bit async character.

SW3-4 Auto RTS (Fast-Poll Mode Only)

SW3-4 ON = Enable Auto RTS

OFF = Disable Auto RTS

For data terminals that do not support hardware RTS, set SW3-4 to ON to enable auto RTS mode. In this mode, TXD is detected at the modem and an internal RTS signal is turned ON. After training completes, the TXD is transmitted to the remote modem. The transmitter turns off if no TXD is detected after 1 character length of idle time. Auto RTS is used in fast-poll mode only (SW3-1 set to OFF).
