Dec 31, 2017 at 19:29 comment added niemiro Okay, top of my head initial guesses (I haven't yet had a chance to test any of these) - ESFE possibly stands for Error Safe F... Encoding (not sure what the F would be, file? failsafe?). For comms purpose (not encryption or compression), and the output is slightly longer than the input? Quite possibly contains parity bits - 1dim or 2dim. "I have never seen anything like it in text books" Hmmm, perhaps not parity bits - or not just parity. "avoiding several bytes such as 'R', nul, xon, xoff etc for certain reasons" - need to consider which system would interpret these characters specifically.
Dec 31, 2017 at 17:42 comment added BmyGuest +1 just for the fact that you've so patiently waited for a hero to come by and solve this :c) I hope my own "still open" questions won't last 20years before anyone cracks them.... 8-) Happy NewYear to you, anyway!
