48 CHAPTER 5. USAGE
Table 5.13 – continued from previous page
Parameter Description
Serial line speed The speed LARA is communicating with the modem. Most of all
modems available today will support the default value of 115200
bps. In case you are using an old modem and discovering prob-
lems try to lower this speed.
Modem Init String The initialization string used by LARA to initialize the modem.
The default value will work with all modern standard modems
directly connected to a telephone line. In case you have a special
modem or the modem is connected to a local telephone switch
that requires a special dial sequence in order to establish a con-
nection to the public telephone network, you can change this
setting by giving a new string. Refer to the modem’s manual
about the AT command syntax.
Client IP address This IP address will be assigned to your console computer during
the PPP handshake. Since it is a point-to-point IP connection
virtually every IP address is possible but you must make sure, it
is not interfering with the IP settings of LARA and your console
computer. The default value will work in most cases.
5.5.7. ISDN Settings
In addition to the standard interfaces, LARA offers remote access using an ISDN connection

.
Logically, connecting to LARA using an ISDN line means nothing else than building up a dedicated
point to point connection from your console computer to LARA. With other words, LARA acts as
an Internet Service Provider (ISP) to which you can dial in. The connection is established using the
Point-to-Point Protocol (PPP). Before you connect to LARA, make sure to configure your console
computer accordingly.
The ISDN settings panel (see Figure 5.26 on page 50 ) allows you to configure LARA for an ISDN
connection. The according ISDN options are described in Table 5.14 .

Parameter Description
Enable ISDN Enables or disables the ISDN adapter.
MSN This Multiple Subscriber Number is assigned to LARA.
Layer-2 protocol The Layer-2 Protocol (the Data Link Layer) of the ISO 7-layered
architecture. It is responsible for the error-free movement of data
between network nodes.
You can choose between the High-level Data Link Control
(HDLC) and X.75.
You can leave this option untouched in case you use a standard
network connection as built in Windows or Linux.
