The further computer (52) uses that is incompatible with port (12). Protocol converters (30, 32, 34 36) between provide translation formats 22, 24). (54) provided utilizes terminals. thus provides capability for substantial number conventional communicate preexisting system in flexible inexpensive manner despite incompatibility formats.
