Abstract

An optical reader, which is operable in a “host commands” mode and a “host routines” mode. In the “host commands” mode, the reader receives and executes a script routine module from a host. In the “host routines” mode, the reader receives a script routine Module identifier from the host, and the reader, in turn, executes a selected one of a plurality of reader-stored script routine modules based on the identifier.

host commands”

mode of operation and a “

host routines”

mode of operation;

(c) a user interface disposed in at least of said host computer and at least one of said N hand held optical readers, enabling an operator to select between said “

host commands”

mode of operation and said “

mode of operation;

(d) wherein said optical reader network is configured so that each said hand held optical reader, upon receipt of a command by an operator input utilizing said user interface to operate in a “

host commands”

mode of operation executes string of script instructions received from said host computer without executing any one of said memory stored script routine modules that are responsive to script routine identifiers;

(e) wherein said optical reader network is further configured so that each said hand held optical reader, upon receipt of a command from operator input utilizing said user interface to operate in a “

host routines”

mode of operation receives at least one script routine identifier from said at least one host processor assembly and executes at least one of said memory-stored script routine modules in accordance with said at least one script routine identifier, wherein said user-interface enables an operator to program a subset of said N optical readers in accordance with said “
