Re: XFree86/QNX SerialRead blocking change

I haven't seen that problem since I am using "devi-hirun" and let
the OS deal with mouse (serial, PS2, or any other qnx supported types).
Touch screen devices can probably be dealt same way, say, "devi-elo".
The good side is we can leave the dirty work to QNX :)

I can understand that sometimes you may need to access the pointer
devices raw. I will pass your email to the XFree86 developers because
the "posix_tty.c" is actually a symlink to
xc/programs/Xserver/hw/xfree86/os-support/shared directory. The symlink
is created dynamicallly during the make. Since "posix_tty.c" is
in the "shared" directory and being shared by other OSes, I want
to make sure your change won't break other people.
Thanks for all your work!
