| 81 | This option supports the 2232 7-port serial card shipped with the | ||
| 82 | Amiga 2000 and other Zorro-bus machines, dating from 1989. At | ||
| 83 | a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip | ||
| 84 | each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The | ||
| 85 | ports were connected with 8 pin DIN connectors on the card bracket, | ||
| 86 | for which 8 pin to DB25 adapters were supplied. The card also had | ||
| 87 | jumpers internally to toggle various pinning configurations. | ||
| 88 | |||
| 89 | This driver can be built as a module; but then "generic_serial" | ||
| 90 | will also be built as a module. This has to be loaded before | ||
