Couldn't set tty to PPP discipline: Invalid argument
Symptom: the following messages appear before connection is established:

Serial connection established.
Couldn't set tty to PPP discipline: Invalid argument

Diagnosis: pppd has failed to change the pty over to run it in PPP mode. This may be because you have no ppp_async module built for your kernel. Most kernels are built with this already, but if you have customised your kernel you may not have built it.

Solution: rebuild your kernel with CONFIG_PPP_ASYNC set. While you are at it, you should set CONFIG_PPP as well, and both should be set to "m" so that they are built as modules. We've found they don't work compiled statically.

Done. Kernel recompiled statically with new option in
menuconfig
drivers
networking
pppd async
It seems to work. I am still testing if the function is robust.
