Hi,

Is the PPP port available so I can test it? I have a SIO port for LPC17xx. It actually reflects the UARTS buffer, meaning that if len is larger that TX_BUFFER it will chunk the data and send it. This will also allow to declare a larger/smaller TX/RX PPP buffer. As what I have seen over the web sio implementations will not work if len > than your buffer unless you send 1 byte at a time which isnt efficient.

Regards,
Nick

I tested it with the Win32 port from contrib. There is (by now) a working SIO port included which should work with PPPoS. I tested that against window's PPP-Server, which still did not work fully. But given the bugs you found in the code recently, that might have changed. Seeing this nice result, a unix SIO port shouldn't be too hard.
