        First version, released on an unsuspecting world.

1.01    2011-04-03
	Module installation test script now requires (build_requires) Net::Telnet
	Chaged test script for detection of Serial port under unix which was not working on most Linux systems
	Ported Device::SerialPort ability to manually specify a TESTPORT=<DEVICE> when running Makefile.PL/Build.PL
	Added use of Exporter module for optionally importing class methods

1.02    2011-05-08
	Still a few linux systems where my serial port detection failed; modified the test script
	Corrected uninitialized $fh warning in input_log, output_log, dump_log when no argument and telnet connection 

1.03    2011-08-24
	Implemented eof method
	Corrected sleep timer in readwait() which was doing non-blocking reads much faster than 0.1 seconds intervals
	Corrected read() which was not logging to input/dump logs in non-blocking mode for SSH & Serial, if read buffer was "0"
	Login stage variable was not re-initialized correctly after a disconnect(); could cause errors on subsequent login()
