4. COMMAND LINE INTERFACE
4.1 Syntax and procedures
The T.50 International Alphabet 5 (IA5) is used in this document. Only the low-order
seven bits of each character are significant to the modem; any eight or higher-order
bit(s), if present, are ignored for the purpose of identifying commands and
parameters. Lower-case characters are considered identical for their upper-case
equivalents when received by the modem from the DTE. Result codes from the
modem are in upper-case.
4.1.1 DTE command lines
Words enclosed in <angle brackets> are referenced to syntactical elements. The
brackets are not used when the words appear in a command line. Words enclosed in
[square brackets] represent optional items, which may be omitted from the command
line at the specified point. The square brackets are not used when the words appear
in the command line. Other characters that appear in syntax descriptions must as
included as shown.
4.1.2 Command line editing
The character <BS> is interpreted as a request from the DTE to the modem to delete
the previous character.
4.1.3 Command line echo
The modem may echo characters received from the DTE during command state and
online command state back to the DTE, depending on the setting of the ATEn
command. If so enabled, characters received from the DTE are echoed in the same
format as received.
4.1.4 Factory settings
The parameter settings of the modem are pre-configured by the factory defaults.
These factory defaults can be reloaded at any time by using the “restore” command.
The parameter settings will be changed when using any commands, which affect the
configuration of the modem. This changes can be permanently stored by using the
“save” command.
restore
= Restore factory configuration.
save
= Store current configuration.
4.1.5 Escape code sequence
When the modem has established a connection and has entered on-line data mode, it
is possible to break into the data transmission in order to issue further commands to
the modem in an on-line command mode. This is achieved by the DTE sending to the
modem a sequence of three ASCII characters specified by set_esc command. The
default character is '+'. The escape characters will be transmitted transparent to the
remote side.
