I'm not suite sure what you mean. Can you provide an example?


Here's what I tried (with and without readline):

 Welcome to MzScheme v3.99.0.23 [3m], Copyright (c) 2004-2008 PLT Scheme Inc.
 Note: readline loaded
 > (let loop () 
     (sync (current-input-port))
     (printf "hit\n")  
     (read-byte)
     (loop))
 hit
 a
 hit
 hit
 ^Dhit
 ^Dhit
 a
 hit
 hit

Both before and after the first eof, "hit" waits to print until I type
either Ctl-D or Enter.


Thanks,
