From 9400716f56057d9f2fcd7f7ad033dfcb131105a2 Mon Sep 17 00:00:00 2001 From: Jake Mannens Date: Wed, 25 Jul 2018 17:18:18 +1000 Subject: Added missing prototype for puts() in stdio.h. Implemented a basic serial interface using COM0 which can be accessed with the system call sys_puts as well as the library functions rsputs() and rsprintf(). Renamed puts() in con.c to con_puts() and made the function static to avoid interference with the library function puts(). --- include/kernel/con.h | 2 +- include/kernel/sys.h | 3 ++- 2 files changed, 3 insertions(+), 2 deletions(-) (limited to 'include/kernel') diff --git a/include/kernel/con.h b/include/kernel/con.h index 178a0d3..9dd9dbe 100644 --- a/include/kernel/con.h +++ b/include/kernel/con.h @@ -1,7 +1,7 @@ /* * con.h * - * Basic VGA text console.
