>>Umm, thanks Paul, but outside of command.com, DOS is extinct here :) Finally found the charts on the MSDN, though...now, if I can figure out what the code definition abbreviations mean...

>Now you're starting another archaeology thread. AFAIR, most of the code abbreviations had some meaning while they were used for teletype - CAN was a signal to cancel a connection, BEL rang a real bell, LF forwarded the paper one line, CR returned the printing carriage to the left side of the paper... No, I'm not that old to have used the thing, but I knew some people who had to learn these codes, for historical reasons. I've found them described somewhere... some 15 years ago, or so.
