Piping output from sqlplus

I'm having a strange problem reading the output from sqlplus in Cygwin.
Sqlplus is a windows command line program used to access oracle
databases. My command looks something like this...

sqlplus -s <<! | read line
user/password@database
set pagesize 0 linesize 200 feedback off tab off
select col1||chr(9)||col2
from table;
!

This should output one line to stdout with the two values separated by a
tab character. The read command should read it into the variable $line.
On my Solaris system it works perfectly. In Cygwin, $line is empty.

If I remove the "read line", the output displays on the tty just fine.

I though it might be related to the line end characters so I tried
converting them with the dos2unix filter. Didn't work. Neither did tr -d
\\r. Both ways, $line still ends up being empty.

If I replace the "read line" with "od -c" to dump the characters, it
shows the one line as expected.

If I redirect the output to a file, the file contains one line as expected.

If I try to read the output into a variable, I get an empty variable

Any ideas?
