Appendix B: PPP Setup
The PPP (Point to Point Protocol) support enables the operator to establish
TCP/IP communication with the MCU via a telephone line with a modem,
or directly via a serial connection.
In order to use the PPP support, both the remote PC that runs the MGC
Manager and the MCU must be set up.
Currently, only one PPP session is supported by the MCU. This PPP session
can be either via Modem connection or via direct serial connection.
The Modem connection involves attaching a modem to one of the MCU’s
serial connectors. The remote station can then connect to the MCU via the
modem.
The Direct Line connection involves connecting the remote station to the
MCU using a Null Modem cable.
Software Setup
The MCU software includes PPP support that is usually disabled. In order to
activate the PPP support, the file
PPP.CFG must be placed in the directory
c:\MCU\CFG.
The file PPP.CFG contains the PPP configuration parameters. It specifies the
COMM port number to be used by the PPP connection, the type of
connection (Modem or Direct) and several other parameters such as baud
rate and modem initialization parameters.
Except CON_TYPE, all the parameters have default values, and should only
be included in the ppp.cfg file if they have been altered.
The file format is similar to the windows INI files format - text file with
sections.
The modification of the setup file is done manually using the appropriate
text editing application, such as Notepad.
