# However, this will be undefined in two cases:
#
# - When we want the RIL to talk directly to a guest
#   serial device that is connected to a host serial
#   device by the emulator.
#
# - We don't want to use the RIL but the VM-based
#   modem emulation that runs inside the guest system
#   instead.
#
# The following detects the latter case and sets up the
