Linux is known to work with the following serial hardware.
- standard PC serial boards (COM1 - COM4), to which external serial
devices (modems, serial mice, etc...) can be connected
- standard PC internal modems (COM1 - COM4)
- Quickpath Systems Port-Folio 550e (allows IRQs of
3, 4, 5, 9, 10, 11, 12, and 15)
- AST FourPort and clones (4 port)
- Accent Async-4 (4 port)
- Arnet Multiport-8 (8 port)
- Bell Technologies HUB6 (6 port)
- Boca BB-1004 (4 port), BB-1008 (8 port), BB-2016 (16 port)
- Boca IOAT66 (6 port)
- Boca 2by4 (4S/2P)
- Computone ValuePort V4-ISA (AST FourPort compatible)
- PC-COMM (4 port)
- STB-4COM (4 port)
- Twincom ACI/550
- Usenet Serial Board II (4 port)
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.
