Having READ ingest the input without waiting for return key to be hit? [message #88625]

I'm trying to have:

letter=''
READ, PROMPT="Enter a letter", letter

finish waiting for input after the first letter is entered without having to have the user hit return. I tried searching around for solutions but my google-fu/index-reading skills were not up to the task. Thanks for any ideas!

Note that this works well from the commands line, but not reliably in the IDL Workbench (see documentation). Had to find out the hard way... Haje
