Link Configuration File (link.conf)

The link configuration file (/etc/opt/SUNWconn/ppp/link.conf) contains a description of your modem configuration and the dialing information used to make a connection to a remote server.

Modem Configuration

Each modem configuration is identified by the keyword dialup_device. For example:

dialup_device 		pppdev0
	unix_device	ttya
	line_speed 	38400
	modem	Practical 14400 V32bis
	call_setup	dial

The most common keywords that may appear in this part of your link configuration file are:

dialup_device pppdevn

Indicates the start of an asynchronous device definition, and assigns a name to the device.

unix_device device_name

Specifies the serial port used to connect the client to the modem.

line_speed speed

Specifies the line speed for the connection between the client and the modem. For optimum performance, the line speed should be equal to, or greater than, the baud rate of the modem.

modem modem_id

Specifies the type of modem connected to the serial port, and associates the asynchronous device with one of the modem definitions in the file /etc/opt/SUNWconn/ppp/modems. This parameter is set to none for a null modem configuration.

call_setup call_type

This parameter is always set to dial for client configurations.

Dialing Information

Each remote server is identified by the keyword remote_host. For example:

remote_host	 miles
	phone_number 	123456789
	chat_script  	miles.scr

The most common keywords that may appear in this part of your link configuration file are:

remote_host name

Indicates the start of a remote host definition, and associates it with one of the paths defined in the PPP path configuration file (ppp.conf).

phone_number number

Specifies the telephone number used to call the remote host. This can be an extension number if the call is within the same private branch exchange, and must include any special digits required to pass outside a private branch exchange. The telephone number can consist of digits and characters, including special characters such as # and *. A dummy telephone number is assigned for null modem configurations.

chat_script filename

Specifies the name of the file that contains the CHAT script for this connection. By default, the connect scripts for remote hosts are located in the directory /etc/opt/SUNWconn/ppp/script.
