| 25 | 25 | * * pins OP0 and OP2 are connected to the primary serial port: |
| 26 | 26 | * * OP0 is RTS |
| 27 | 27 | * * OP2 is DTR |
| 28 | | * * Attach m68k interrupts properly; I suspect the DUART INT and SPC INTs are both hooked up wrong |
| 29 | 28 | * * Actually store the X2212 nvram's eeprom data to disk rather than throwing it out on exit |
| 30 | 29 | * * is there some way i can hook this up using &generic_nvram? |
| 31 | | * * emulate/simulate the MT8060 dtmf decoder as a 16-key input device? |
| 30 | * * emulate/simulate the MT8060 dtmf decoder as a 16-key input device? or hook it to some simple fft code? |
| 32 | 31 | * * discuss and figure out how to have an external application send data to the two serial ports to be spoken |
| 33 | 32 | * |
| 34 | 33 | * LED error code list (found by experimentation and help from leeeeee): |
