Hi:
I want to add pppoe support into qnx4 by porting pppoe linux driver. Does
the pppd in qnx4 support pty option? If not, Is it doable to port linux ppp
and pppd driver into qnx4?
Is current ppp stack inside the qnx kernel?
Do I need to modify qnx kernel in order to support pppoe? If yes, Is there
anyway to resolve this problem since we don’t have qnx kernel source code?
Can we license it?
Any plan for qnx to support pppoe on qnx4? Any timeframe?
How can I add pppoe support under qnx4? Any suggestions?
Thanks,
Jackie
Lots of questions

No. It does not support pty option. And yes, it is “doable” to
write a “qnx4 pppoe driver”. I am not sure about linux ppp/pppd,
but I trust they are the same code base with qnx4’s.

No. Nothing is in qnx “micro kernel”. But the ppp stack is inside
the Sock[l]et (the tcpip stack) in Tcpip 4.25.

You don’t need to modify “QNX kernel”, and I seriously doubt you
could license the source code
Any plan for qnx to support pppoe on qnx4? Any timeframe?
Not that I know of, so no timeframe.

You best bet is write a “raw packet” driver, deal with ethernet, and it
also act as a “io manager” so pppd/Sock[l]et could read/write
it just as a serial device.
