Over the last few days, I've been trying to get Scheme (both
scm and STk) to give me input, using all of the port-reading functions
I could find (read, read-char...) to get it to input data, but
it refuses to recognize the input unless it's terminated by a
carriage return.  Is there any way to get it to stop buffering each
line like this?

(i.e. I'd like it, when presented with input like:
abcdefg#[eof] to give me the abcdefg *and* the #[eof], not just
the #[eof]; abcdefg#[newline]#[eof] works, however.)

Thanks,
Chris
