摘要

The present invention concerns a system (1) and a process for acquiring a software code (SW) in a device from a host computer, a host computer and a software transmission process. The system comprises receiving means (11) of at least one code portion of the software code, at least two competing available code portions (Sik) being proposed simultaneously to the device for being downloaded, delaying means (13) sending to the computer for each competing portion, successive negative acknowledgements (NAK), and selecting means (14) of the code portion to be received among the competing available ones, the delaying means stopping sending the negative acknowledgements for the selected portion, so that the receiving means receive only the selected portion.
