DA Systems Inc has launched a new service that will enable subscribers to its DASnet Service to send binary or ASCII text files to people who use the electronic mail systems linked by the DASnet Service, which it claims includes most major systems: the development work was sponsored and part-funded by Connect Inc, Cupertino, California, Twics BeeLine, Tokyo, and Unison Telecommunications Service, Cincinnati, all of whom offer the DASnet Service and its inter-system messaging as a standard feature.
