[Qemu-devel] qemu/vl.c serial patch termios fix

[Zach Metzinger]

Hi-

The serial routines do not set the proper termios flags for the serial
port so that data can pass unmolested from the emulated environment to
the host serial device. This simple patch fixes that. Tested on a 
FreeBSD 6.2 host with Windows XP as the emulated OS.
