# Supported serial hardware

Linux supports, (ie is known to work with):

- standard XT PC serial boards
- standard internal modems

Multiport serial boards:

- Usenet Serial Board II
- Boca 4-port (BB-1004)
- Boca 8-port (BB-1008)
- Boca 16-port (BB-2016)
- AST FourPort boards and clones

In general, Linux will support any serial board which uses a 8250, 16450, 16550, or 16550A (or compatible) UART.

Linux does not currently support any intelligent serial boards, but will likely do so sometime in the future.

Special note on the BB-1004 and BB-1008, they do not support DCD and RI lines, and thus are not usable for dialin modems. They will work fine for other purposes.
