 * isol.c (was isolconsole.c)
 *      IPMI Serial-Over-LAN console application
 *
 * Author:  Andy Cress  arcress at users.sourceforge.net
 * Copyright (c) 2007 Intel Corporation
 * Copyright (c) 2009 Kontron America, Inc.
 *
 * 10/12/06 Andy Cress - created, just a framework for now
 * 02/08/07 Andy Cress - now working for IPMI LAN 2.0 SOL in Linux,
 *                       still stdio problems in Windows
 * 02/23/07 Andy Cress - fixed Windows stdin, still Windows output issues,
 *                       need more in xlate_vt100_win().
 * 04/06/07 Andy Cress - more vt100-to-windows translation, 
 *                       added -r for raw termio
 * 04/19/07 Andy Cress - more vt100-to-windows translation, 
 * 05/08/07 Andy Cress - more logic for 1.5 SOL.  Session opens but 
 *                       1.5 SOL data packets are not yet working.
 * 05/24/07 Andy Cress - Fix Enter key confusion in BIOS Setup (use CR+LF)
 * 06/15/07 Andy Cress - More fixes to Windows translation (fUseWinCon)
 * 08/20/07 Andy Cress - moved Windows translation to isolwin.c
 * See ChangeLog for further changes
 *
 * NOTE: There are a few other options for Serial-Over-LAN console 
 * applications:
 *   ipmitool.sf.net has v2 sol console capability for Linux (BSD)
 *   Intel dpccli, a CLI console for Linux and Windows (proprietary)
 *   Intel ISM console for Windows (proprietary)
 *   Intel System Management Software (LANDesk) console, proprietary 
 * The Intel applications support both IPMI 1.5 and 2.0 SOL 
 * protocols.
