2 Supported serial hardware

• Usenet Serial Board II
• Boca 4-port (BB-1004)
• Boca 8-port (BB-1008)
• Boca 16-port (BB-2016)
• Boca 6-port (IO/AT66)
• AST FourPort boards and clones
• Accent Async boards
• Bell Technologies HUB6
• STB-4COM

In general, Linux will support any serial board which uses a 8250, 16450, 16550, 16550A (or compatible) UART, or an internal modem which emulates one of the above UARTs.

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 all other purposes.
