virtualbox.org

I'm running VB 1.5.6 on a Windows Server 2003 host. HW is a Dell PowerEdge T105 server.

I have enabled the serial port on my Windows XP guest via the Settings->Serial Ports dialogue in the VB GUI. The settings I've used are:
Port Number: COM1
Port Mode: Host Device
Port Path: COM1

The Windows XP virtual machine starts with no issues - but the guest OS does not see any COM ports at all. I've verified the COM port is working fine via the host OS using hyperterminal and a modem. The port also appears in Device Manager on the host box. But no matter what I try the COM port never appears in Device Manager on the guest box.

Is there more configuration required to get the COM port working on the Guest machine?

I had the same problem. I solved it by adding new hardware in guest Win XP. And Windows found the new HW for COM1. After it it worked.

set 1?in the setting page, you configurate the com1 0x3F8 IRQ4 , namedpipe \\.\\pipe\guest-com1

step 2?run the windows xp guest

step 3: in the control panel, you run the new hardware program.

setp 4: following the step, choice new hardware item, then the guest os will detect com1.
