Subject: [PATCH 18/25] efi-stdio: Implement setting cursor visibility
Date: Mon, 13 Dec 2021 22:08:58 +0100 [thread overview]
Message-ID: <20211213210905.3399551-19-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20211213210905.3399551-1-s.hauer@pengutronix.de>
The sequence "\b[?25h" makes the cursor visible and "\b[?25l" makes it
invisible. Implement support for this sequence.
