Advanced Options

RS232 OPTIONS. The following screens are used to configure the RS-232 interface.

DTR OPTIONS. Use the ◊ 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 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 ◊ 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 NOR- MAL IN CB to disable this feature. Same as the &C5 and &C4 commands.

CTS OPTIONS. Use the ◊ 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 screens 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 〈⇓ and buttons. To go to the next position, press the ◊ button. To back up or to exit without saving, press the ◊ 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 button. To go to the previous screen, press the ⇓ but- ton. To go to the next screen, press the ◊ button.

TIME TO RESTORE (S15). Sets how frequently leased line restoral attempts occur when the modems are in dial backup mode. The restore time interval can be set from 10 to 255 min- utes in one minute increments. A value of 0 disables dial back- up. 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.
