Definition of "unintermitted"

The only action taken by Mr. Dosson in consequence of his elder daughter's revelations was to embrace the idea as a subject of daily pleasantry. He was fond, in his intercourse with his children, of some small usual joke, some humorous refrain; and what could have been more in the line of true domestic sport than a little gentle but unintermitted raillery upon Francie's conquest?
