[lwip-users] ppp-new threading question

[Ivan Delamer]

I feel almost embarrassed asking this but I haven't completely figured 
it out yet.

In ppp-new, are packets sent to sio_write() from tcpip thread, or from 
the RX process thread? Or both?

I just ask because sio_write() may block for some time (at least in my 
basic implementation) and I'm wondering if this is blocking the rest of 
the stack.

Cheers
Ivan
