At present, you will need to handle the initial connection from the
remote end yourself. There is no standard mechanism for doing this in
eCos. You may, for example need to check a password or parse some
commands to indicate that PPP should be started. However, once that is
done, the standard PPP API calls should then just bring up the PPP
link in the ususal way.
