Do the same as for a modem, except drop all the modem specific stuff.

On the ppp server:
1)      Configure the serial port (setserial).
2)      Run pppd on the serial port with the passive option.
        ( pppd ttySx passive ... )

On the client do the same, although the passive option would not be
required.

If your server setup is permanent like, you'll probable have to add a
"respawn" statement (can't remember the file name, but it's the one
that runs your gettys, etc.) to re-run pppd once a connection is
dropped.

Hopefully .... Volla

 
 
 

1. ppp-serial line looped backed

Does anyone have any idea what is happening here.  Most of the time I
can connect just dandy.  Other times I get this in the message log

I have RH5.1 with all the stock stuff loaded.  The only thing that seems
to remedy the situation is to either unplug the phone line from the
modem (56k internal, but was doing it with a 28.8 internal as well) or
go into minicom and do a modem reset.  As soon as I do one of those two
things I can run the ppp-on script and it works perfectly.  It all
started when I had the phone company test my lines for DSL
compatibilty...any ideas?
