2. 已經支援的串列硬體

以知 Linux 可以與下列的串列硬體配合運作．

2.1 標準 PC 串列埠

• 標準 PC 串列埠 (COM1 - COM4)，能夠讓外接的串列裝置(數據機，串列滑鼠等)連接的
• 標準 PC 內接式數據機 (COM1 - COM4)
• Quickpath Systems Port-Folio 550e (可用的 IRQ 為 3, 4, 5, 9, 10, 11, 12, 及 15)

注意: 由於位址衝突，你不能同時使用 COM4 及 IBM8514 視訊卡．這是 IBM8514 視訊卡的一個 bug．

2.2 即插即用型(PnP)數據機

即插即用型數據機能夠在 Linux 上運作．然而，我不建議使用它們，因為有困難． 你有好多事情要試:

• 試著關掉你電腦 BIOS 及數據機上的 PnP 功能．
• 啟動 Windows 95，設定數據機，然後看看在你啟動 Linux 後這些設定能否保留下來． 如果不行的話，再來:
• 啟動 Windows 95，設定數據機，然後使用暖開機啟動 Linux 以便讓設定能保留下來． 你可以使用 loadlin 載入器來啟動．
• 從 http://www.redhat.com/linux-info/pnp 取回 PnP 工具．
• 然後你就有個可用的數據機．

2.3 一般多埠串列卡(附 8250/16450/16550A UART 晶片)

• AST FourPort and clones (4 ports)
• Accent Async-4 (4 ports)
• Arnet Multiport-8 (8 ports)
• Bell Technologies HUB6 (6 ports)
• Boca BB-1004 (4 ports), BB-1008 (8 ports), BB-2016 (16 ports)
• Boca IOAT66 (6 ports)
• Boca 2by4 (4 serial ports, 2 parallel ports)
• Computone ValuePort V4-ISA (AST FourPort compatible)
• Digi PC/8 (8 ports)
• GTEK BBS-550 (8 ports)
• Longshine LCS-8880, Longshine LCS-8880+ (AST FourPort compatible)
• Moxa C104, Moxa C104+ (AST FourPort compatible)
• PC-COMM (4 ports)
• Sealevel Systems COMM-2 (2 ports), COMM-4 (4 ports) and COMM-8 (8 ports)
• SIIG I/O Expander 2S IO1812 (4 ports)
• STB-4COM (4 ports)
• Twincom ACI/550
• Usenet Serial Board II (4 ports)

一般來說， Linux 能夠支援所有使用 8250, 16450, 16550, 16550A（或與其相容）UART 晶片的串列卡， 或者是能夠摸擬上列 UARTs 之一的內接式數據機．

注意: BB-1004 以及 BB-1008，它們並不支援 DCD 及 RI 線路，因而無法讓接受撥接的數據機使用． 它們在其它用途上則表現正常．

2.5 不支援的串列硬體

宣稱``Winmodems''的數據機，例如 USR Sportster Winmodem 及 IBM Aptiva MWAVE， 無法在 Linux 上使用．這些數據機具有專門的設計需要特別的 Windows 驅動程式． 避免使用這樣的數據機．除此之外，基於相同理由也別使用需要 Rockwell RPI 驅動程式的數據機．

沒有 Linux 所需驅動程式的智慧型串列埠也不能使用．
