  Intelbras TI630 telephone
  Driver by Felipe Correa da Silva Sanches <juca@members.fsf.org>

  http://images.quebarato.com.br/T440x/telefone+ks+ti+630+seminovo+intelbras+sao+paulo+sp+brasil__2E255D_1.jpg

  Changelog:

   2014 JUN 17 [Felipe Sanches]:
   * Initial driver skeleton
   * LCD works

================
    Messages displayed on screen are in brazilian portuguese.
    During boot, it says:

"TI auto-test."
"Wait!"

    Then it says:

"Initializing..."
"Wait!"

    And finally:

"TI did not receive"
"the dial tone"

It means we probably would have to emulate a modem device for it to treat communications with a PABX phone hub.
================
