Serial converter. This emulates an FTDI FT232BM chip connected to host character
device @var{dev}. The available character devices are the same as for the
@code{-serial} option. The @code{vendorid} and @code{productid} options can be
-used to override the default 0403:FF00. For instance,
+used to override the default 0403:6001. For instance,
@example
