tty_putchar() is not the routine that is called when receiving data.
tty_putchar() does exactly the same thing as what `tputchar()' used to
do, namely print a system message to the TTY.

The routines you are probably looking for, are ttydisc_rint(),
ttydisc_can_bypass() and ttydisc_rint_bypass(). Please take a look at
http://wiki.freebsd.org/TTYRedesign how to use them. Good luck!
