Good day, ladies and genlemens.
I collide with issue decribed at https://www.virtualbox.org/ticket/1548.
I use VirtualBox 4.2.6 build 82870 under Xubuntu 12.04 LTS AMD64 for emulate Windows XP prof SP3. Some time ago I see that data received in XP (115200, 8 bit of data, no parity, no flow control, 2 stop bits) from my hardware temporary out of trend. Now I check this ussie.
For tight coverage today I use GtkTerm for send 8k pseudo-random data from Xubuntu (ttyS1) to XP (ttyS0 mirrored to COM1). Normally I use under XP "Br@y terminal" and today I try to use standart Hyperterminal aslo. I use same setting as I use with my hardware. In attaced files you can see outgoing data (noise8k.bin) and differences between reseived and transmitted data (bray.txt, hterm.txt).
As I see - Br@y lost approx. 1k series byte after receive first 1k bytes. Hyperterminal - lost by one byte randomly and swap bytes.
