UARTS in WinXP

Hello,
using VB 4.0.0 in openSUSE11.2 (64bit) I enabled a serial line in the VB. The installed WindowsXP does not see any COM. Doesn't matter, whether the COM should be disabled or connected to /dev/ttyS0.
Any hint would be highly appreciated.
Best Regards
uho

There are 3 parts to a serial connection: the simulated guest hardware, the physical host hardware, and the connection between them. All three parts must be working and/or correctly configured before you will have any success.
Simulated guest hardware first: If you enable a serial port in the VM settings then the simulated guest hardware exists and will be visible to the guest, even when the simulated serial port is not connected to anything physical. Typically you will create a virtual COM1 inside the guest. Note however that serial ports are not plug and play devices in Windows - you may have to use the guests "Add new hardware" feature if the serial port was enabled after the guest Windows was installed.
Getting the host hardware working is of course beyond the scope of this forum.
Connection to a host device: Once the simulated guest hardware exists you choose what host interface to connect it to. A pulldown menu gives you your choices: disconnected (connected to nothing physical), connected to a named physical serial port, or connected to a named pipe.

This was the problem. Deeply hidden in the guest I found it. Now, it sees COM1, as expected.
Many Thanks!
