As usual, I have little of interest to provide; but I would like to express appreciation and thanks to DDGator, R9Scarry, theirishguard, yankee2500, tracker, kjtrains, ACP,P7Enigma, Richard S, birdman, ccoorreeyy and all the others who contribute constantly and informatively to this forum.
The help and information provided here is invaluable, and by far the best source for technical data, expert no BS opinions (well, usually) and occasionally some good humor.
Thank you all, sincerely.
PS: ccoorreeyy: the problem with the doubled letters in computer screen input/ouput is often caused by incorrect UNIX-related stty 'echo keyboard character' settings in your terminal emulation setup. This likely could be corrected if needed.
