This part is the last thing missing, we are about to solve the last
issues about the binding, but we still didn't have your opinion about
issuing commands from the ->set_ios() callback and Adrian required it to
take this series.

To have more context you can have a look on:

it is the original email where Adrian wanted your agreement.

Thanks,

Gregory
