How to Define Communications Over the Serial Line

1. Become superuser on the dial-out machine or assume an equivalent role.

   Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services. To configure a role with the Primary Administrator profile, see Chapter 2, Working With the Solaris Management Console (Tasks), in System Administration Guide: Basic Administration

2. Create a file that is called /etc/ppp/options with the following entry:

   lock

   The /etc/ppp/options file is used for defining global parameters that apply to all communications by the local machine. The lock option enables UUCP-style locking of the form /var/spool/locks/LK.xxx.yyy.zzz.

   ---

   Note –

   If the dial-out machine does not have an /etc/ppp/options file, only the superuser can run the pppd command. However, the /etc/ppp/options can be empty.

   ---

   For a complete description of /etc/ppp/options, refer to /etc/ppp/options Configuration File.

3. (Optional) Create a file that is called /etc/ppp/options.ttyname for defining how communications should be initiated from a specific serial port.

   The next example shows an /etc/ppp/options.ttyname file for the port with the device name /dev/cua/a.

   # cat /etc/ppp/options.cua.a crtscts

   The PPP option crtscts tells the pppd daemon to turn on hardware flow control for serial port a.

   For more information about the /etc/ppp/options.ttyname file, go to /etc/ppp/options.ttyname Configuration File.

4. Set the modem speed, as described in How to Set the Modem Speed.
