Also, the serial port has to be enabled in the virtual BIOS (under "Avanced" -> "I/O Device Configuration"). You should then see something like this with the dmesg command:
Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing enabled serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A 00:08: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A |
