chvt does not (cannot) change the file descriptors of the shell, so
although you switch to tty3, that's not where the shell's stdin is
coming from.
I'm almost certain you need something like:
exec < /dev/tty3 > /dev/tty3
before the chvt line.
(As I said before, "ls -l /proc/self/fd" is your friend.)
