DTE Dialer Configuration Options
*AT Cmnd Mode: Normal
Nxt Normal No_ERROR NoStrapOrERR
AT Command Mode. Determines how the modem responds to valid and invalid AT commands.
NOTE: Since this configuration option affects AT commands, it cannot be changed by the AT&F command. However, it
can be changed by selecting a factory preset configuration via the DCP.
Normal – Allows normal operation of the AT command set. The modem acts upon all valid AT commands and issues the
ERROR result code for invalid commands. If a string with multiple commands is entered, then an invalid command within
that string will prevent the execution of subsequent valid commands.
No ERROR – Operates similar to Normal mode, however, the modem does not issue an ERROR result code for invalid
commands. When an invalid command equivalent is encountered, the modem ignores it and issues the OK result code.
If a string with multiple commands is entered, then an invalid command within that string will not prevent the execution of
subsequent valid commands.
No Strap or ERROR – Ignores all AT commands (including valid commands) that cause a configuration option to
change. Only nonconfiguring commands (for example ATD, ATA, and ATI) are executed; the ERROR result code is
never returned.
The factory default is Normal.
AT command equivalent is S-register S84=
n
DTR Cont Repeat: Disable
End Disable Enable
DTR Cont Repeat. Determines whether automatic redialing stops after the directory locations defined by DTR Auto
Redial (S37) have all been tried unsuccessfully once. If DTR Cont Repeat is enabled, automatic redialing starts again
with directory location 1. The default is Disable.
A redial attempt is made in response to a bad phone number, a busy signal, no answer, or no quiet answer. However, a
lockout from redialing occurs if ten successive failing call attempts are made to the same number.
DTR Cont Repeat is accessible only if the DTE Dialer Type is DTR=Dirs.
Disable – Automatic redialing will not be repeated.
Enable – Automatic will be repeated if necessary.
AT command equivalent is S-register S38=
n

* This configuration option only appears if DTE Dialer Type is configured for AT.
