DTE Dialer Configuration Options
*ResultCode Form: Words
Nxt Words Numbers (1) Numbers (2)
Result Codes Format. Controls whether or not result codes appear as words or as numeric codes. Some DTEs do not
recognize Result Codes as words; therefore, numbers are required. The Numbers (2) format is required for some
modem pooling applications. (For a list of result codes, refer to Table B-1 in Appendix B.)
The factory default is Words.
AT command for Numbers (1) is V0.
AT command for Words format is V1.
AT command for Numbers (2) is V2.
*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 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 is S-register S84 =
n
, where
n
is 0 or 231 for Normal, 1 or 232 for No ERROR, or 2 or 233 for No Strap or
ERROR.
V25bis Coding: ASCII
Nxt ASCII EBCDIC
V.25bis Coding. Identifies to the modem whether the DTE is using ASCII code or EBCDIC code for V.25bis commands.
The modem responds to the DTE using the same coding.
NOTE: This configuration option only appears if DTE Dialer is configured for V25bis HDLC or V25bis Bsync.
The factory default is ASCII.
AT command is S-register S62 =
n
, where
n
is 0 for ASCII or 1 for EBCDIC.
V25bis IdleFill: Mark
Nxt Mark Flag
V.25bis Idle Fill. Determines whether a mark or flag is used as an idle fill character for the DTE. The modem responds to
the DTE using the same idle fill.
NOTE: This configuration option only appears if DTE Dialer is configured for V25bis HDLC.
The factory default is Mark.
AT command is S-register S63 =
n
, where
n
is 0 for Mark or 1 for Flag.
* This configuration option only appears if DTE Dialer Type is configured for AT.
