# Dedicated 86Box serial-system UART policy.
#
# MartyPC's IBM PC/XT-compatible serial devices expose the original 8250
# programming model.  Fixing both active ports to that model makes sersys test
# the same byte-wide registers on 86Box instead of accepting a newer UART after
# auto-detection.  Polling also prevents COM2 trace writes from contending with
# an interrupt-driven tty owner while the trace path writes the 8250 directly.
