    Try this:

    write yang /dev/pts/6
#type your message
#ctrl + D (EOF)

    see: man 1 write

    or echo "message" > /dev/pts/6

  2. ~# tty
/dev/pts/89
~# echo hello to myself >/dev/pts/89
hello to myself

    or

    ~# echo hello to myself >`tty`
hello to myself

    or to write several lines:

    ~# cat >>`tty`
hello
from another
