AT * DL2 =60 60-ms delay before the modem sends CTS to the DTE after receiving RTS from the DTE.
AT * DL3 =90 90-ms delay before the modem sends CTS to the DTE after receiving RTS from the DTE.
AT * DL4 =S26 RTS/CTS delay is determined by the value of S-Register 26.
Pause Delay Pause Delay
Makes the modem pause when it encounters modifiers in a dial string or on the command line.
AT * DP0 =3 Pause delay is 3 seconds.
AT * DP1 =6 Pause delay is 6 seconds.
AT * DP2 =9 Pause delay is 9 seconds.
AT * DP3 =12 Pause delay is 12 seconds.
AT * DP4 =S8 Pause delay is determined by S-Register 8. See the “S-Registers” section in Chapter 5.
Auto Redial Auto Redial
Determines how many times the modem redials a failed call. The modem waits for a country-
specific time between redials. If the AT
* LN option is enabled, the modem dials all of the
linked numbers before redialing.
AT * DR0 =Off The modem does not redial an unsuccessful call.
AT * DRn =n The modem redials an unsuccessful call n times (n=1-15).
AT * DSn or
AT * DS=n
Dial From
Stored#
=n
Dialing a Stored Telephone number (n=1-9)
See the ATDS description earlier for information on using this command.
DTR Delay DTR Delay
Determines how long the modem waits after connecting to the dial line before examining the
DTR signal from the DTE. If the DTR signal is low, the modem disconnects. This feature is
used when AT Form =SyncData or V25 Form=AsynSync.
AT * DT0 =S25 The modem waits for the time specified by S-Register 25 before examining DTR.
AT * DT1 =10 sec The modem waits 10 seconds before examining DTR.
AT * DT2 =15 sec The modem waits 15 seconds before examining DTR.
EC Error Correction
The AT * EC (EC) command determines which error-correction protocol is used. NOTE: This
option does not apply when the modem is configured for SDC operation. If both the local and
remote modems are operating in SDC mode, LAPM error correction with V.42bis data
compression only is used; no other setting is available.
AT * EC0 =V.42 The modems negotiate the use of LAPM or MNP error correction. First, the modems attempt to
negotiate using LAPM. If unsuccessful, they attempt to negotiate using MNP.
AT * EC1 =LAPM The modems attempt to negotiate LAPM error correction.
AT * EC2 =MNP The modems attempt to negotiate MNP error correction.
Fast Call Fast Call
Reduces the time for selected phases of the connect sequence.
AT * FC0 =Off This option disables the Fast Call feature.
AT * FC1 =Lvl1 The 2.15 second billing delay in the answer modem is eliminated. The length of time ABT is
sent is reduced by 1 second in all modulation modes except V.34.
