Configuring kppp.

Here's what worked for me, submitted in hopes it will help another 
UNIX/Linux rookie.

My ISP uses PAP authentication on their dial-up PPP server.

1. Log in as root.

2. Add the following to the file /etc/rc.d/rc.serial 
   stty 57600 < /dev/cua0 # set the modem port to 57600.

3. Setup a symbolic link to /dev/cua0 from /dev/modem
   ln -s /dev/cua0 /dev/modem

4. Reboot and log in 
     or 
   Enter the command 'stty 57600 < /dev/cua0' then logout and log in 

5. startx

6. Open kppp

7. Configure kppp 

   7.1 My kppp configuration - not including many defaults
       Accounts
         Dial
           Authentication = PAP
               Execute program on connect = xrefresh (eliminates or 
               diminishes a "feature" in pppd (or is it an X or KDE 
               bug?) that makes KDE go black)
           pppd arguments = -detach /dev/modem 57600 crtscts defaultroute
         IP
           Dyanmic IP Address = On
           Auto configure host name from this IP = Off
         DNS
           IP addresses of your DNS 
           Domain = blank
           Disable existing DNS services during connection = On
         Gateway
           Default
         Logon script
           Use default script = On
         Accouting
           not enabled
    
       Device
         modem = /dev/modem
         flow control = ctsrts
         line term = cr/lf
         speed = 57600
         modem lock file = /var/lock/LCK..modem
         time out = 60 sec
      
       Modem
         modem assets CD line = Off
         modem commands (for US Robotics 28.8 Sportster V42.bis)
           Initialization: AT &F &D2 &H1 &B1 Q0 X4 &A3 S7=75 S0=0
               For US Robotics 28.8 Sportster V42.bis. Spaces added 
               to improve readability. They are not entered in kppp.
           others at default settings
      
          # Explanation of Initialization commands
          # &F  Reset to Factory Defaults
          # &D2 Normal DTR Operation
          # &H1 Hardware Flow Control
          # &B1 Fixed serial port rate
          # Q0  Result codes displayed
          # X4  Result code option
          # &A3 Protocol codes enabled
          # S7=75 Number of seconds to wait for carrier
          # S0=0  Turn off answering
      
       PPP
         pppd path = /usr/sbin/pppd
         timeout = 90
         log viewer = kedit
         disconnect on Xserver shutdown = On
         minimize window on connect = Off

   7.2 Another way to set up kppp is to edit your kppprc file 
       Notes:
       1. *** indicates a parameter you need to edit 
       2. ### indicates a comment. Comments must be deleted.
       2. Lists: Elements are comma delimited and end with a comma. 
                 See pppdArguments list for an example

--- end of $HOME/.kde/share/config/kppprc ---

8. When done configuring, click Connect on the kppp control panel

   The connection went through and I got a dialog much like the dial
   up connection in Windows 95.

  Thanks to all of you helping people like me to get some sort of PPP going. The point I'm at now is I can get kppp to connect to my ISP (or netcfg via usernet,) and I can get Netscape to run, but I don't seem to get netscape to actually use the ppp connection. Kppp's statistic box shows bytes and packets going out and in, but it's slow to the point of a freeze, and I don't really know if anything of merit is going on between the two applications.
  Any help/hints would be welcome about now.
