Control commands
ELSA MicroLink 56k Internet

Control commands
The AT command set (AT = command prefix for Attention) was not standardized until
recently. The implementation was left to the discretion of the individual manufacturers.
A standard now exists in the V.250 command set. Microsoft recommends the use of this
command set for the 'PC 98' specifications and prescribes its use for the 'PC 99'
specification.
With your
ELSA MicroLink 56k Internet , you have purchased a state-of-the-art modem
equipped with the AT command set in accordance with V.250.
A terminal program is required to enter AT commands from the PC (e.g.
ELSA-
COMMUNICATE! Lite
).
Entering and executing AT commands
After switching on, the modem is in the command phase. Commands can only be
accepted, interpreted and executed in this phase.
In the event that several commands are to be sent to the modem, these may be entered
individually, each with an AT command prefix and a concludingC. It is also possible,
however, to enter these commands consecutively in a single command line after an
introductory AT and to conclude the line with an C.
The individual commands may be separated by spaces to improve the overview. No
further characters may be entered once the end of the command line buffer has been
reached. The command line can then only be edited with H(backspace) or executed
with C.
Escape command
Use the characters -mand -Xto abort a command line or a screen output
(e.g. in case of displaying the register contents use AT%R).
Commands that must be specified with a parameter may also be entered without a
parameter. The absence of a parameter corresponds to the parameter 0
(e.g. ATL=ATL0 ).
After the successful establishment of a connection to the remote site, the modem
switches from the command phase to the transfer phase.
Transfer phase means that a connection to a remote data station (i.e. to another modem)
exists: The modem is online. This is the case after successful call establishment
(outgoing call), as well as after answering a call (incoming call). The exchange of data
between two data stations can take place during this phase.
A renewed transition to the command phase and back, also in the case of an existing
connection, is possible with the escape command and the command ATO. The escape

Control commands
ELSA MicroLink 56k Internet
12
command consists of a series of three escape characters (default setting: +++) and a valid
command line.
After the three Escape characters have been entered, the modem is in the command
state. Data transfer is not interrupted until a valid command line has been recognized.
The escape character has nothing in common with the character ;of the ASCII
character set. It can be redefined in register S2.
All commands sent to the modem must begin with the ASCII characters AT or at (not
valid: At or aT) and must be concluded with C. A valid command line in an escape
sequence is restricted to a maximum of 40 characters.
The command AT&F loads the firmware default parameter settings. This command is
not executed during existing connections.
Bit-oriented registers
Bit-oriented registers are primarily used to provide status information. Please note that
the modification of a single value in the bit-oriented register may have several functions.
Great caution should thus be applied when changing bit-oriented registers! To change
the configuration of your modem, you should use the AT commands instead. A complete
description of the S-registers can be found on the ELSA modem CD.
Modifying bit-oriented registers
The following example will illustrate the modification of the bit-oriented options of a
register. To set the bit 6 of register S14, enter the command ATS14.6=1.
If you would like this value to be maintained after the modem is switched off, the new
entry can be stored with the command AT*W.
Overview of AT command set and registers
In this brief overview, which is grouped according to topics, you find frequently needed
AT commands and registers you can use to change your modem settings. A complete
description of the AT command set and registers can be found on the CD which comes
with the modem.
The “Commands and registers” column lists AT commands and registers you can use to
change the basic settings of the modem. The “More commands and registers” column
lists AT commands and registers for extended control of the modem.
