install drawterm or conterm.

    $ doas pkg_add drawterm


currently, drawterm doesn't ask for username on OpenBSD. however, you can emulate it easily.

    $ cat /usr/local/bin/sshdraw.sh
    #!/bin/sh
    echo -n 'user[glenda]:'
    read duser
    if [ $duser ]; then
            drawterm -r /var/empty -G -u $duser
    else
            drawterm -r /var/empty -G -u glenda
    fi


create a user for connecting into, for example, "drawterm". then append the following to /etc/ssh/sshd_config

    Match User drawterm
            ForceCommand sshdraw.sh
            X11Forwarding no
            AllowTcpForwarding no
            AllowAgentForwarding no
