27# Many devices using the FT232R chip are not "classic" serial port
28# modems at all - and for those devices, hardware designers seem
29# quite casual about configuring some of the modem status lines
30# - in particular carrier detect, which is often left floating.
31# Even "regular" serial ports are often 3-wire configurations.
32#
33# Given the usage is rarely as a fully-fledged modem, this configuration
34# file makes the default for the driver to ignore the state of the
35# carrier detect line; set this property to zero, or comment it out to
36# have the device provide full "modem" semantics
37#
38# Note that 'ignore-cd' applies to all ports supported by the driver
39# while the 'port-N-ignore-cd' applies only to port N
