PPPL modems

Once those options are set, close the `Edit Phone' window and check that the options on the other menus are set to desired values (i.e. 2400 baud, 8 data bits, no parity, 1.0 stop bits for both Courier and Concord). Very importantly, make sure the `DEC VT100' under the `Emulation' menu is checked. To begin dialing, select your modem type in the `Phone' menu and wait. Once the connection has been established (on Concords, the word `Initiating' appears), press RET every few seconds until Princeton Plasma Physics Lab., etc. appears. And then you will be asked to give username and password. The password here is only for the pppl dial-up service. You can select a password and register it with our Help-Desk at 2275. For security reasons, please do not use your computer password here. The following is what you may see on the screen during the dial-up process:

        CDS> DM2925
        CDS> NUMBER = M2925   
             DIAL TONE
             DIALING M2925.....s

            Username:  smith 
            Password:  XXXXX 
            PPPL Connection successful, pause 4 sec., press return
        Local> set port flow disable        
        Local> telnet suntsu

At the prompt, type in set port flow disable. This allows your commands (which may have some special meaning to the terminal server) to be sent to the remote host as normal commands. (i.e.---If you are running Emacs on Lyman from home, you want to be able to use the search function, CTL-s, without it telling the server to stop the flow of information.) From then on, follow the procedures for a telnet login. To logout, just type logout both at the host prompt and the Local> prompt.
