No, its waiting for input after sending escape. Escape + character is how you reach the C1 control codes, with CSI and OSC (ESC + '[' and ESC + ']') being popular ones (both referred to in the posted article). This is relevant for keyboard input (as contrasted to output-only) since some codes for special keys (like arrow keys) start with CSI. Edit: You asked about the terminal emulator, but its the console application that has to do the wait.
