PPP support in ET1 Android kernel

Hello everybody

 

Is ET1 Android kernel compiled with PPP support and/or CONFIG_PPP_ASYNC flag?

 

When trying to start pppd daemon (part of a customer application) the system returns the following error:

 

 

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

Google insists that the most possible reason for this kind of error is that the kernel has been compiled without ppp_async support. Is this the case for ET1?

 

Thanks,
Valery
