Technical Examples
When electronic mail with firmware attached is received at a data communication apparatus, determination is made whether it corresponds to firmware data of a write process allowable state. In the case of write process allowable data, the message is downloaded from a mail server to a printer controller. Then, derived firmware is transmitted to an image formation apparatus. A firmware rewrite permission is obtained. When the firmware attached to the message does not attain a write process allowable state, waiting is conducted for reception of write process allowable firmware with the data left in the mail server. As a result, a data communication apparatus is provided that can rewrite firmware appropriately independent of a transmitted and received order of divided firmware.
