Abstract
A method and apparatus for facsimile communication uses subaddress messages sent from a sending facsimile terminal to control how a facsimile image transmission is to be handled, e.g., routed and/or translated, by a receiving facsimile terminal. The invention may be employed through the use of an adapter which is designed to work with existing facsimile terminals which are incapable of generating subaddress messages. The invention, when employed with 10-key facsimile machines which cannot generate by the keys thereof proper subaddress delimiting symbols, automatically transforms non-permitted transmission symbols generated by the key to permitted transmission symbols.
