Hello all,

I'm trying to paste some text into a DOS program (using alt-space, e, p),
but see just a few chars appear (many are lost).

That problem doesn't occur when pasting at the COMMAND.COM prompt. So
chances are that your DOS program's use character based input and clears the
keyboard buffer each time.

I would like to try to use a slower char-buy-char pasting to see if that
helps, but could not find any such speed setting (using Google). Does
anyone know if 1) its possible 2) if so, how to change it ?

There's no such setting. Clipboard is not designed with performance
throttling.

You'll just have to create custom application or AutoIt/AutoHotkey script to
paste the text one character at a time. By preparing a character in the
clipboard from the source text, then send the WM_COMMAND window message for
the console's "Paste" menu. Repeat that until all characters are processed.
