| 5 | * Based in the radio Maestro PCI driver. Actually it uses the same chip |
| 6 | * for radio but different pci controller. |
| 7 | * |
| 8 | * I didn't have any specs I reversed engineered the protocol from |
Mauro Carvalho Chehab | 4286c6f | 2006-04-08 16:06:16 -0300 | [diff] [blame] | 9 | * the windows driver (radio.dll). |

| 11 | * The card uses the TEA5757 chip that includes a search function but it |
Mauro Carvalho Chehab | 4286c6f | 2006-04-08 16:06:16 -0300 | [diff] [blame] | 12 | * is useless as I haven't found any way to read back the frequency. If |

Mauro Carvalho Chehab | 4286c6f | 2006-04-08 16:06:16 -0300 | [diff] [blame] | 27 | * BUGS: |
