Apparatus and method providing improvements in establishing a data path between local and selected remote equipment over non-dedicated telephone lines. The present invention provides for the detecting of signalling activity during period not normally monitored, to provide a system which is resistant to accidental interruptions during the initial establishment of the data path, and includes apparatus, such as an external programmable code repeater insertable between the calling computer and the telephone line to overcome limitations of typical modems and modem software. Also included are further features offering greater flexibility in applications and permitting further compatibility with differing or more limited hardware and software systems.
