  No, this box has only 1 serial port.

  My case is:

[    1.469295] Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports,
IRQ sharing enabled
[    1.469450] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[    1.470113] 00:09: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[    1.470312] serial 0000:00:1f.6: enabling device (0000 -> 0001)
