Hi David -

You can use get_option and set_option to set/get various bits in the
win DCB or posix termios. These pins are not currently described as
far as I can tell.

Options implement the SetabbleSerialPortOption and GettableSerialPortOption.

Take a look at serial_port_base.hpp for the existing options (such as
baud_rate). You will find the implementation in impl/serial_port_base.ipp.

It should be fairly easy to use those as a guide to make your own
options that support your platform. For window you will modify the DCB
structure and for posix the termios.
