Hello all . I'm new to this list.
A few days ago I asked on xen-users mailing list if xen and qemu serial
driver code is related. Someone there confirmed that. After some digging
and trying different serial port configurations I can say that problem
below is protocol related.
I hooked up two boxes with serial cable. First one is WinXP on real
hardware, second one qemu (or xen) virtualized WinXP on FC6.
I started Hyper Terminal on both sides. Console communication is OK.
Then I tried file transfer.
1. Real to virtual file transfer is good, other way not possible - using
Zmodem protocol
2. Both ways file transfer is good - using Kermit protocol
If I try same thing on non virtual boxes, I don't have this problem no
matter what protocol I use.
The problem is that I can't change protocol when using proprietary
application (for Win only) and this special device on COM port.

On the other way, emulated serial port is not acting the same as real
one. Is this question for xen or qemu developers? Can I try anything else?
I can provide additional info if someone is interested, but I'm not a
programmer to fix this problem :)
Thank you.
Aleš
