DTE Interface Configuration Options

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 RS-232D operation. 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. Valid only in Synchronous mode and Asynchronous Direct mode.

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.

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 equivalent is &Rn.

CTS Control: Forced_On

Clear-to-Send Control. CTS is a signal from the modem to the DTE indicating that it can accept data from the DTE.

NOTE: When CTS flow control or CTS/RTS flow control is enabled, CTS will turn ON and Off regardless of the setting of CTS Control.

Forced On ± CTS is forced ON at all times. Use this selection for most asynchronous applications.

Standard RS232 ± In Synchronous mode, forces the state of CTS to follow the state of RTS in normal RS-232D operation. The minimum time that elapses between CTS and RTS is determined by the RTS/CTS Delay configuration option. Use this setting for most synchronous applications.

In AT Command mode, CTS (which is ON in Idle mode) goes Off just prior to DSR going active, and goes ON when the modem enters Data mode. This operation prevents losing data in applications which begin transmitting as soon as DSR and CTS are both active.

Wink When Disconnect ± CTS is normally forced ON, but is turned Off for 1 to 2 seconds upon a disconnect. Use this for most UNIXr applications.

Follows DTR ± The state of CTS follows the state of DTR. When DTR turns ON, CTS turns ON. When DTR turns Off, CTS turns Off.

For Async Dial, Forced On is the factory default.

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

For UNIX Dial, WinkWhenDisc is the factory default.

AT command equivalent is \Dn.
