Queue symbol field recovery flags for defining boundaries of one or more fields of a document read by a reader sorter

摘要

A Reader/Sorter may have an MICR read head, an OMR read head, and two OCR read heads or a combination thereof. A Reader/Sorter Adapter receives characters read by the Reader/Sorter. The characters include data and formatting symbol characters read from a document and control characters generated by the Reader/Sorter. Certain characters may be identified as queue field identifiers (QFI) by the user via software. These are usually the formatting characters. The control characters are identified as pseudo queue field identifiers (PQFI). QFI and PQFI characters are received by a Multiple Device Controller and allow the firmware to identify the length of the data fields, the head from which the characters were received, and any special conditions associated with reading of a data field.
