CAT Commands
From The Unofficial FT-897 Wiki
CAT lets you control the radio from a computer - a better description will be put up sometime. For instant reading see the manual, it explains it and the serial format and parameters required.
Undocumented Commands
| Name | P1 | P2 | P3 | P4 | Opcode | Notes | |
| Read EEprom | MSB | LSB | 0x00 | 0x00 | 0xBB | Returns 2 bytes, the specified address and the 'next' address. 16 bit memory addressing, unused memory returns 1 byte (for me 0xf0). |
Interesting Memory Locations
| Address | Name | Values |
| 0x0068 | VFO | 0x80=VFO-A 0x81=VFO-B |
| 0x008D | Split | 0x00=No split, 0x80=split |
