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.

Abstract: An apparatus comprising: a sensor array having rows of pixels which are exposed to symbol indicia, wherein the sensor array generates a sync signal; an aiming pattern generator for producing an aiming pattern superimposed on the symbol indicia; a processor which utilizes the sync signal to control the aiming pattern generator to: turn on the aiming pattern during exposure of a first predetermined row of pixels; turn off the aiming pattern during exposure of a second predetermined row of pixels; turn on the aiming pattern during exposure of a third predetermined row of pixels; and, a housing for housing the sensor array, aiming pattern generator and processor for hand held operation.
