setToInitConsole

public static void setToInitConsole(FileDescriptor fd)

Set console to initial terminal settings.

readVirtualKey

public int readVirtualKey(InputStream in)
                   throws IOException

Description copied from class: Terminal

Reads a virtual key from the console. Typically, this will just be the raw character that was entered, but in some cases, multiple input keys will need to be translated into a single virtual key.

Overrides:

Parameters:

in - the InputStream to read from

Returns:

the virtual key (e.g., ConsoleOperations#VK_UP)

Throws:

IOException

isSupported
