The text console currently does not recognise these\nstring-type introducers, so each byte of the payload is interpreted as\na normal character or a new escape, producing garbage on screen.\n\nAdd a TTY_STATE_OSC state that silently consumes all bytes until the\nsequence is terminated by BEL or ST (ESC \\).\n\nReviewed-by: Daniel P.
