Advanced Options 
RS232 OPTIONS 
The following LCDs are used to configure the RS-232 interface. 
DTR OPTIONS 
Use the Æ and Enter buttons to select how the modem responds to the high to 
low transition of the DTR signal sent by the computer. DTR NORMAL causes the 
modem to hang up; IGNORE DTR allows operation with computers that do not 
provide DTR; and RESET ON DTR È causes the modem to perform a soft reset 
as if the Z command were received. Same as the &D0&D2, and &D3 
commands. 
CARRIER DETECT OPTIONS 
Use the Æ and Enter buttons to select whether CD will be forced high (CD 
FORCED ON
) or whether it will go high when the remote modem’s carrier signal 
is detected, and go low when the carrier signal is not detected (CD NORMAL). 
Same as the &C0 and &C1 commands. When using callback security on UNIX 
systems, select CD LOW IN CB to force CD low until the proper callback security 
password has been entered or until a disconnect occurs. This prevents the UNIX 
login prompt from being displayed before the callback security ENTER 
PASSWORD prompt appears. Select CD NORMAL IN CB to disable this feature. 
Same as the &C5 and &C4 commands.  
LINUX OPTION 
The connect message will display after the proper callback security password is 
entered. 
CTS OPTIONS 
Use the Æ and Enter buttons to select whether the CTS state will follow the 
RTS state when on line (CTS NORM) or whether CTS will always be high 
(CTS ON). Same as the &R0 and &R1 commands. 
DIALBACKUP/LL OPTIONS 
The following LCDs are used to configure dial backup for four-wire leased line operation. 
For more information, see Chapter 4, “Leased Line Operation.” 
DIAL BACKUP NUMBER 
Use to enter a dial backup number. To scroll through a list of digits and 
characters, press the Ç     Å  and È buttons. To go to the next position, press the 
Æ
 button. To back up or to exit without saving, press the Æ button several times. 
To save the number, press the Enter button. Note: Only 16 characters can be 
displayed at a time. To see characters 17–30, press the È button. To go to the 
previous LCD, press the Å button. To go to the next LCD, press the Æ button. 
TIME TO RESTORE (S15) 
Sets the leased line restore attempts occur when the modems are in dial backup 
mode. The restore time interval can be set from 10 to 255 minutes in one minute 
increments. A value of 0 disables dial backup. Same as the S15= command. 
DIALBACKUP TIME (S17) 
Use to set how long the modem waits after a leased line failure before it attempts 
a dial backup connection. The timer can be set from 1 to 255 minutes in one 
minute increments.  Same as the S17= command.
