From 117d073a602490e284a22f09222a2504a5768b39 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Fixed wrong use of datatypes. In wait_for(), a char was used
 together with getchar(), in readchar(), a char was used to read input, which
 in getuchar() is used as an argument to islower() and toupper(). Also removed
 a condition which terminated the process if the user typed in character 255.
 Approved by christos.
