I'm not sure you understand fully what a PPP connection gives you. A PPP 
connection is a means of providing a transport for the TCP/IP stack. You 
cannot communicate directly over it. Instead you use socket calls, or with 
lwIP you can use the sequential API. To do that you have to establish a 
connection with the remote peer's IP address.

If you want to just send a plain string over the serial line, then you 
don't want to be using PPP on it at all.
