| 11 | |
| 12 | 2014 JUN 17 [Felipe Sanches]: |
| 13 | * Initial driver skeleton |
| 14 | * LCD works |
| 15 | |
| 16 | ================ |
| 17 | Messages displayed on screen are in brazilian portuguese. |
| 18 | During boot, it says: |
| 19 | |
| 20 | "TI auto-test." |
| 21 | "Wait!" |
| 22 | |
| 23 | Then it says: |
| 24 | |
| 25 | "Initializing..." |
| 26 | "Wait!" |
| 27 | |
| 28 | And finally: |
| 29 | |
| 30 | "TI did not receive" |
| 31 | "the dial tone" |
| 32 | |
| 33 | It means we probably would have to emulate a modem device for it to treat communications with a PABX phone hub. |
