Missing characters using serial port.
Posted: 14. May 2008, 15:36
When I use the serial port in Windows XP, I miss characters during receiving.
Serial port params are 115K2 8N1 (no flowcontrol).
This happens when an external 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.
So it should be a bug in VB?
Is this a common problem in VB?
