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.
================
