From 9f4b48a15d2dce4ae243920cdc83d46cc0eb4896 Mon Sep 17 00:00:00 2001 From: darylm503 Date: Fri, 21 Dec 2012 18:19:41 +0000 Subject: StdLib: Fix issue with Canonical output expansion of NL to CR NL and similar expansions. SysCalls.c: Add IGNSPEC to the "sane" termios settings so that, by default, function keys and other special keys are ignored. fvwrite.c: Line 109: Change test to less-than zero since zero is a valid value. Line 113: Change test to greater-than zero since we only want to loop when there are characters available. Line 114: Force uio_resid to zero since it might have become negative on line 113.
