Nope. There is no bug to fix. Scroll lock says to stop output, so the tty buffer fills up after a while and the tty driver sleeps on "ttywri". Workaround: `comcontrol /dev/console drainwait 10' times out the sleep after 10 seconds. write() returns -1/EIO or a short count. Applications may be confused by this. EIO normally means hangup.
