ABSTRACT:
An interface between a system processor of an automated mailing system and selected peripheral devices carries peripheral support hardware and software for communication with the peripherals. The interface includes a board having a memory wherein programs for formatting communications with the peripherals are stored. A working memory for the temporary storage of commands and data for communication to the peripherals and a peripheral controller for establishing a communications link with a selected peripheral are also carried on the interface board. The inclusion of additional peripheral devices or the substitution of alternate peripheral devices which would require revision of communications formatting programs does not require reprogramming of the system processor and is accommodated by revising the program stored in the interface program memory.
