Running the following code and typing cntl-c at the prompt results in an
I/O error from stty on Linux, AIX, Solaris. The version on Linux is
Version AJM 93t+ 2010-02-02; others are ksh88. Bash does not cause an
stty error.
How can I write similar code (with a pipeline) to avoid this issue?
Thanks!

#!/bin/ksh
{
trap 'stty echo; exit 1' INT
stty -echo
printf "prompt: "
read pw
stty echo
trap - INT
echo "<$pw>" >&2
} | cat
