How 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 table lists basic settings for modems that use Solaris PPP 4.0.

   Table 31–3 Modem Settings for Dial-up PPP

   Parameter	Setting
   DCD	Follow carrier
   DTR	Low so that the modem hangs up (puts the modem on-hook)
   Flow Control	RTS/CTS for full-duplex hardware flow control
   Attention Sequences	Disable

   If you have problems in setting up the link and suspect that the modem is at fault, first consult the modem manufacturer's documentation. Also, a number of sites on the World Wide Web 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.

4. Run admintool, as explained in “Setting Up Terminals and Modems” in System Administration Guide: Advanced Administration.

   1. Click the port where you have attached the modem, either port a or port b.

      The Modify Serial Port window is displayed.

   2. Specify modem direction as dial-out only.

      Although you can set up the modem as bidirectional (the default template for admintool). The dial-out-only choice is more secure against possible intruders.

   Note –

   You can set the baud rate and timeout from admintool, however, the pppd daemon ignores these settings.
