-This directory contains three useful packages related to the termios I/O
-system:
-
-PACKAGE SERDBGIO
-================
-"serdbgio" provides the "serial gdb" standard I/O functions "getDebugChar"
-and "putDebugChar" for any device driver supporting polled termios mode. 
-
-The initialization function "serdbg_open" opens the v.24 port intended
-for the serial debug connection, and sets the desired baud rate. The
-"getDebugChar" and "putDebugChar" functions then interact with the
-corresponding driver using the calls intended for polled termios
-operation.
-
-Specification for the debug device, baud rate and other parameters is
-done in a global structure of type "serdbg_conf_t". A configuration
-mechanism quite similar to the overall RTEMS configuration is available.
-
-PACKAGE SERDBG
-==============
-"serdbg" provides a means to optionally initialize and/or start a
-serial gdb session as soon as possible, this means as soon as all
-drivers have been initialized. The serial debug I/O functions can
-either be integrated as special routines of the BSP drivers, or using
-the package "serdbgio"
-
-PACKAGE TERMIOS_PRINTK
-======================
-"termios_printk" provides a standard output function suitable to use
-with "printk". It uses the same technique as serdbgio, hooking the
-interface between a polled device driver and the termios system. 
-
-
-REQUIREMENTS
-============
-
-- These two packages can be used with any polled termios device
-driver. 
-- For standard initialization, they need a modified "bsppost.c"
-to perform the initialization calls.
-
-USAGE
-=====
-
-For using these packages add the following to your "init" module or
-your "system.h" file (Note: most macro settings fall back to a
-default, if not set.):
-
-/*
- * CONFIGURE_USE_SERDBG
- * set this macro, if you want to connect gdb over a serial line
- * when set, the debug stub will be connected after driver
- * initialization in "bsppost.c"
- */
-#define CONFIGURE_USE_SERDBG
-
-
-/*
- * CONFIGURE_SERDBG_SKIP_INIT_BKPT
- * set this macro, if you do not want the gdb interface to wait for a
- * debugger connection directly after initialization
- * If you set this macro, the gdb stub will only hook various
- * exception vectors when called from "bsppost.c".
- */
