Managing Serial Networks Using UUCP and PPP in Oracle^® Solaris 11.4

How to Configure the Modem and Serial Port on a Dial-Out System

1. Program the modem.

   Even though a variety of modem types is available, most modems are shipped with the correct settings for Oracle Solaris PPP 4.0. The following list shows the basic parameter settings for modems that use Oracle 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 system and to the telephone jack.
3. Become an administrator on the dial-out system.

4. Specify modem direction as dial-out only.
