From fa748f3e1c0b0571e2c53514a55794ca16d90b18 Mon Sep 17 00:00:00 2001 From: Danny Holman Date: Fri, 16 Feb 2024 12:35:04 -0600 Subject: arch: i386: kernel: the serial driver should be more POSIX-y Make the serial driver behave more like a standard POSIX call. It should have write and read functions that call architecture specific functions.
