Hi Giacinto,
Besides, several modules use the option linux driver, which blocks in
case the port doesn't answer.
This single call:
g_at_chat_unref(port);
blocks either 30s or 1 minute, depending on the system. I might step
into it twice during my hardware initialization for several 3G models.
It helps to run this line on a separate thread unblocking the rest.
What system call blocks (use strace to determine this) ? If anything
inside the option driver blocks for 30-60 seconds, that is unacceptable
and needs to be fixed in the kernel.
Regards,
-Denis
