5.5.6 Modem Settings
RAS-PutIn offers remote access using a telephone line in addition to the standard access over the
built-in Ethernet adapter. The modem needs to be connected to RAS-PutIn’s serial interface.
Logically, connecting to RAS-PutIn using a telephone line means nothing else than building up a
dedicated point to point connection from your console computer to the RAS-PutIn. With other
words, RAS-PutIn 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 RAS-
PutIn, make sure to configure your console computer accordingly. For instance on Windows
based operating systems you can configure a dial-up network connection, which defaults to the
right settings like PPP.
The Modem Settings panel allows you to configure the remote access to RAS-PutIn using a
modem. The meaning of each parameter will be described below. The modem settings are part
of serial settings panel (Figure
5.22 on the facing page).
ˆ
Enable modem on RS 232
Enable or disable the modem on the serial interface adapter of RAS-PutIn. In case it is
enabled, RAS-PutIn tries to initialize the modem using an initial string of AT commands
and waits for incoming connections.
ˆ
Serial line speed
The speed RAS-PutIn 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 problems try to lower this speed.
ˆ
Modem Init String
The initialization string used by RAS-PutIn 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 connection 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.
ˆ
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
