From efa51f2bd641965f91550e1f7eeec14b5746db87 Mon Sep 17 00:00:00 2001 From: Sean Anderson Date: Mon, 4 Apr 2022 14:17:58 -0400 Subject: [PATCH] serial: sandbox: Implement puts This implements puts for sandbox. It is fairly straightforward, except that we break out the shared color printing functionality into its own function.
