1. GENERALITY
This operating manual describes the installation procedures and the main
featuresof the Leonardo56 modem family. Leonardo 56 isthe perfect modem
fax sulution for applications that require ultra high speed and reliability over a
remote user analog line: the ideal solution for data, and fax, communication
for professional, office or the home user.
This operating manual is for the following modem: Leonardo 56 external
RS232 & USB (PC or Macintosh), Leonardo 56 internal ISA card (PC) and
Leonardo PC Card (PC and Macintosh). See the details of the installation
procedure of your enviromental in the installation chapter.
DEAR CUSTOMER,
Your Leonardo 56 complies with the 56Kbps standard
accordingto the ITU-TV.90regulationfor data communication
up to 56000 bps.
The V.90 standard, like the K56Flex, has an unbalanced
connectionspeed.It means thatyou have aconnectionwhere
data are received at the maximum speed of 56000 bps and sent at the
maximum speed of 33.600 bps.
The unbalance, due to the technical limitations of the analog telephone lines,
allows to carry out connections with top performances in applications of
Internet access or remote access.
In order to reach the connection speed of 56000 bps, according to the 56K
technology, one of the two modems must be connected to a digital network
(usually ISDN or *64 in G703/G7047). In fact, the modems of the Services
Provider (Internet POP or access servers) are special ones, like "Central
Site Modem"(CSM).
Themaximum speed,when receiving data, in users connections over analog
line is 33.600 bps.
ADDITIONAL AT COMMAND FOR 56K
Your Leonardo 56 has been tested with the most popular Communication
softwarerunning on PC or Macintoshplatforms: thecorrect initialisationstring
to enable 56K speed is:AT+MS=12,1,300,56000,1,0

LEONARDO 56 Modem AT Command Set
3.1
3. MODEM AT COMMAND SET
The modem supportAT commands set to define the configuration, initiate or
terminate modem communication, test the modem and the communication
link. The modem will work in two basic operations: command mode and
data mode.
Command mode is when the modem is not connected to another modem,
therefore “Off Line” or in a idle condition. In this mode the modem will accept
commands beginning with AT prefix. Data mode is when the modem is
connectedto another modem, that isan “On Line” condition orfunctioning. In
this mode all the characters sent from computer are interpreted as data and
they are sent to the remote modem. You may switch from data to command
mode by entering an escape sequence. The default escape sequence is +++
this must have at least one second before and after being keyed. To go back
into data mode simply type ATO.
Data Length
Each caracter of the AT command must be an ASCII code with any of the
following format combinations:
START BIT DATA BIT PARITY STOP BIT TOT
171110
180110
170210
181111
The modem will accept even, odd, mark, or space.
3.1. AT COMMAND SET DESCRIPTION
AT Attention
All the characters following the letters ‘AT’ are commands. In AT command
modethe modem automaticallydetects the computerspeedand parityformat.
