DSR Control: Stndrd_RS232

Nxt Stndrd_RS232 Forced_On WinkWhenDisc Follows_DTR On_Early Delay_ToData

Data Set Ready Control. DSR is a signal from the modem to the DTE indicating the modem is connected and ready for operation.

HStandard RS232

Allows the modem to control DSR to the DTE. The modem raises DSR when it begins the handshake process. DSR lowers upon disconnect. The modem is not ready to receive data until DSR, CTS, and LSD are active. An ON state indicates to the DTE that the modem is ready to receive data. An OFF state indicates that the modem is not ready to receive data, and the DTE will not send data to the modem. During a Local Analog Loop and a Remote Digital Loop, DSR is ON.

HForced On

Forces DSR output ON constantly. This is usually used for leased-line applications and when the DTE requires DSR to always be ON.

HWink When Disconnect

DSR is normally forced ON, but is turned OFF for 1 to 2 seconds upon a disconnect.

HFollows DTR

When the modem receives DTR from the DTE, it sends DSR to the DTE.

HOn Early

DSR is low when the modem is in the idle state. DSR goes high immediately upon a command to enter Data mode. This setting is required for some modem pooling applications.

HDelay to Data

Operation is similar to the Standard RS232 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.

The AT command for Forced On is &S0.

The AT command for Standard RS232 is &S1.

The AT command for Wink When Disconnect is &S2.

The AT command for Follows DTR is &S3.

The AT command for On Early is &S4.

The AT command for Delay to Data is &S5.
