> -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.):
