.Stream.Term.SetAttr (gb.term)

Sub SetAttr ( Mode As Integer, Settings As TerminalSettings )

Sets the parameters associated with the terminal from the Settings argument.

The Mode argument specifies when the changes take effect:

Term.TCSANOW	The change occurs immediately.
Term.TCSADRAIN	The change occurs after all output written to the stream has been transmitted. This option should be used when changing parameters that affect output.
Term.TCSAFLUSH	The change occurs after all output written to the stream has been transmitted, and all input that has been received but not read will be discarded before the change is made.

This method is a direct interface to the tcsetattr() system function.
