Missing characters using serial port.

[Teuniz]

When I use the serial port in Windows XP on a Linux host, I miss characters during receiving. Serial port params are 115K2 8N1 (no flowcontrol).

This happens when an external hardware device is sending a continues datastream to the serial port at the highest baudrate (115K2). It looks likes Virtualbox is not able to handle all the data in time (empty the receivebuffer). When I use a native Linux application to receive the same data at the same baudrate without flowcontrol, no characters are missing. When I use Windows XP without virtualizing, there are no missing characters. The host is OpenSUSE 10.3.
