cyg_io_write(),sio_send(),sio_write()
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.
