Matt Anderson 0458833072 cc3200: Make telnet login procedure work with Tera Term.
This is actually a workaround Ter Term's issue of not obeying to the
telnet options that the server is sending. Therefore, we must buffer
chars until either a '\r' or the max length of the username/password
is received.
