Try:

$set term/perm/notypeahead TTDXXX:

VMS will not allow logins on a port set like this(actually it will not prompt
or anything).  If application needs to have typeahead set, then it
can be set when the application is called, and the permenant characteristics
will again take effect when the port is closed.
