At Command Set - INSYS 56k small INT 2.0 Operating Manual

AT Command Set

9 AT Command Set
All INSYS communication devices are controlled internally via AT commands.
A terminal program is integrated in the HSComm. The AT commands can be di-
rectly entered at the menu item "Terminal".
Alternatively, we recommend the terminal program TeraTerm by T. T. Teranishi.
The free software can be downloaded at

Each AT command starts with the letters AT and ends with a "Carriage Return"
(CR). Capital and small letters will both be accepted, but the leading characters
must be either 'AT' or 'at'. The command line is evaluated after the modem re-
ceives a return command. In the description, a parameter with the letter "n"
means that it can have various values.
For example, ATL<n>, where 'n' can have the value 0 or 3, e.g. ATL2 (medium
volume). For commands which expect a parameter but don't have a parameter,
the modem will automatically assume the parameter 0. For example, the com-
mands ATZ and ATZ will have the same effect.
The factory settings are marked "(default)".
The standard end character is "return" (oDh) or "<CR>". "Return" may not be
entered after "****" or "+++".
The commands are acknowledged with "OK" or "ERROR". A com-
mand that is being edited will be interrupted by any further incoming
character. Therefore, the next command must wait for acknowl-
edgement to avoid the deletion of the current command.

Note: The installation of the driver files creates a
virtual serial interface (COM port) on the com-
puter. The PC will treat this interface like a
"real" serial interface. All commands and func-
tions in this manual which relate to serial inter-
faces can also be used for the version INSYS Mo-
dem 56k small INT USB 1.0.
