| 3 | ======================= |

| 5 | QEMU implements some PCI serial devices which are simple PCI |
| 6 | wrappers around one or more 16550 UARTs. |
| 7 | |
| 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. |

| 29 | Name: |
| 30 | ``pci-serial-2x``, ``pci-serial-4x`` |
| 31 | PCI ID: |
| 32 | 1b36:0003 (``-2x``) and 1b36:0004 (``-4x``) |
| 33 | PCI Region 0: |
| 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. |
| 36 | Interrupt: |
| 37 | Wired to pin A. |
