[Xen-users] Xen serial console has only 7 bit?

I tried to use the Xen serial console, as described in http://wiki.xen.org/wiki/Xen_Serial_Console . I also used the resulting xvc0 device as a console of the DOM0 Linux.

Everything was working fine, and I could explore the features of the Xen console. Almost everything... Finally I discovered, that when logging in to Linux on the serial console, I could not use german umlauts. It seemed as if the most significant bit was masked off during input.

After a long search, what I was doing wrong I saw this line of code inside the Xen serial driver:


OK, this explains the behaviour. But what is the intention of this line? Shouldn't this actually be something like

if (handle & SERHND_HI)
    c &= 0x7f;
return c;
