We run a port selector, which types a fair amount of message-of-the-day to
the user's terminal; but this might happen even without a port selector.

If the terminal is in a slow scrolling mode it can't always keep up with
incoming characters at 2400 baud, so it will try to restrain input with
ctrl-S, and follow with ctrl-Q when it catches up.  We found this happening
with the initial getty message and login: prompt.  The result is that the
user's login name is prefixed by ^S^Q and the first attempt to log in always
fails.  I'm wondering if there is any reason not to modify getty and login
to strip out any funny characters in the login name.
