DTE Interface Configuration Options

DSR Control (cont’d)

Delay to Data – Operation is similar to the Standard RS232 setting except that DSR does not turn ON until the modem enters Data mode. Normally, the modem raises DSR when it begins the handshaking process.

Use this setting when the DTE cannot operate with a long DSR-to-CTS delay (common for V.32bis modulation) or when dial access security is enabled and requires a DTE-side password entry. Often, the DTE cannot accept the long delay between DSR and CTS turning ON due to the remote user entering the DTE-side password.

Dial Backup Toggle – DSR is turned off during a dial backup attempt in Leased mode, and on when such an attempt completes. DSR is also turned off when a disconnect begins, and turned on when the disconnect is complete.

For Async Dial and UNIX Dial, Forced_On is the factory default.

For Sync Dial and Sync Leased, Stndrd_RS232 is the factory default.

AT command for Forced On is &S0.

AT command for Standard RS232 is &S1.

AT command for Wink When Disconnect is &S2.

AT command for Follows DTR is &S3.

AT command for On Early is &S4.

AT command for Delay to Data is &S5.

AT command for Dial Backup Toggle is &S6.

RTS Action: Ignore

Nxt Ignore Stndrd_RS232 Sim_Cntl_Car Cntl_Car

Request-to-Send Action. RTS is a signal from the DTE to the modem indicating the DTE has data to send to the modem.

Ignore – Modem assumes RTS is always ON. Use this selection when the DTE does not provide RTS to the modem.

Standard RS232 – Allows the DTE to control RTS to the modem in normal EIA-232-D operation. In direct mode, RTS must be ON for the DTE to transmit to the modem.

Simulated Control Carrier – RTS input controls the remote modem’s LSD signal. This is used for DTEs that require Line Signal Detect (LSD) to toggle ON and Off to simulate half-duplex operation.

NOTE: If RTS Action is set for simulated control carrier, then the remote modem’s LSD Control configuration option must be set for Simulated Control Carrier. Simulated Control Carrier conforms to V.13 specifications. This setting is ignored when the modem is configured for Asynchronous mode and RTS/CTS flow control is selected.

Control Carrier – Allows the DTE’s RTS signal to control the modem’s carrier signal. When RTS is ON, carrier is present on the VF line. When RTS turns Off, carrier is no longer present. This is only valid for V.29 leased-line modulation, if installed.

For Async Dial and UNIX Dial, Ignore is the factory default.

For Sync Dial and Sync Leased, Stndrd_RS232 is the factory default.

AT command for Standard RS232 is &R0.

AT command for Ignore is &R1.

AT command for Simulated Control Carrier is &R2.

AT command for Control Carrier is &R3.
