2 QEMU PCI serial devices
3 =======================
5 QEMU implements some PCI serial devices which are simple PCI
6 wrappers around one or more 16550 UARTs.
8 There is one single-port variant and two multiport-variants. Linux
9 guests work out-of-the box with all cards. There is a Windows inf file
10 (``docs/qemupciserial.inf``) to set up the cards in Windows guests.
21 IO bar, 8 bytes long, with the 16550 UART mapped to it.
30 ``pci-serial-2x``, ``pci-serial-4x``
32 1b36:0003 (``-2x``) and 1b36:0004 (``-4x``)
34 IO bar, with two or four 16550 UARTs mapped after each other.
35 The first is at offset 0, the second at offset 8, and so on.
