ProcedureHow to Configure the Modem and Serial Port (Dial-out Machine)

  1. Program the modem.

    Even though a variety of modem types is available, most modems are shipped with the correct settings for Solaris PPP 4.0. The following list shows the basic parameter settings for modems that use Solaris PPP 4.0.

    • DCD – Follow carrier instructions

    • DTR – Set low so that the modem hangs up and puts the modem on-hook

    • Flow Control – Set to RTS/CTS for full-duplex hardware flow control

    • Attention Sequences – Disable

    If you have problems setting up the link and suspect that the modem is at fault, first consult the modem manufacturer's documentation. Also, a number of web sites offer help with modem programming. Finally, you can find some suggestions for clearing modem problems in How to Diagnose Modem Problems.

  2. Attach the modem cables to the serial port on the dial-out machine and to the telephone jack.

  3. 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.

  4. Run the /usr/sadm/bin/smc command, as explained in Setting Up Terminals and Modems With Serial Ports Tool (Overview) in System Administration Guide: Advanced Administration. This command opens the Solaris Management Console.

    Use the Solaris Management Console to do the following.

    1. Select the port where you have attached the modem.

    2. Specify modem direction as dial-out only.

      You can set up the modem as bidirectional. However, the dial-out-only choice is more secure against possible intruders.

    Note –

    You can set the baud rate and timeout from /usr/sadm/bin/smc. However, the pppd daemon ignores these settings.
