As I use TTY device of eCos, the default mode is ECHO. But it seems TTY only
echo back inputs when user call its tty_read() function.

When I worked on VxWorks before, once its TTY device opened, it always echo
back inputs NO MATTER whether user call its read function or not. I think it
do this in the callback of the Rx interrupt of serial device.

So which of the behaviors is reasonable?
