In view of the fact that a limited storage area of a facsimile memory cannot
store
a large amount of data necessary to operate and manage the facsimile machine, a
hard disk of a personal computer connected to the facsimile machine is used for
storing such a large amount of data. For example, an application software needed
for achieving a certain function of the facsimile machine is supplied from a service
station managed by a manufacturer of the facsimile machine and is downloaded and
installed in a hard disk of the personal computer. An example of the function is
a scheduled/delayed transmission for scheduling a time of facsimile transmission
at a specific time or after a certain period of time has passed. As far as the
facsimile machine and the personal computer are connected, other kinds of data,
such as help list data and facsimile transaction information, are stored in the
hard disk of the personal computer.
