Method of passing instructions between a host station and a portable electronic device, and device for implementation

摘要

The method includes in placing an instruction presence parameter in the argument field of a binary word defining a read/write command generated by generic management programs (drivers) for removable data storage units. This makes it possible to circumvent the limitation of the set of the commands authorized by a generic program for managing a removable data storage unit, without running the risk of data being interpreted wrongly as instructions.
