Is your feature request related to a problem?

No, i just need to use uart flow control.

Describe the solution you'd like

Enable support for flow control (RTS and CTS, perhaps it would be also usefull to enable DTR and DSR)

Describe alternatives you've considered

Add a parameter on the "begin" function that allows to select if the serial should use CTS/RTS and a pin assigment (might be just adding de pins, and if they are different than -1 the flow control would be enabled).
Also a "setRts" and "setCts" function could be implemented to enable one or both flow control pins
