Abstract

A facsimile communication system comprises a facsimile unit and a host computer which is connected to the facsimile unit through a telephone line, wherein settings of functions of the facsimile unit are read out or altered by input operations on the input unit of the host computer.

Claims

1. A facsimile communication system comprising:

a facsimile unit having storage means for storing a plurality of selectively alterable operating parameters for controlling the operation of the facsimile unit;

a host computer connected to said facsimile unit through a telephone line;

means for reading the operating parameters of said facsimile unit with said host computer over the telephone line;

an input device connected to said host computer; and

means for altering at least one operating parameter in said storage means of said facsimile unit with said input device over the telephone line.

2. The facsimile communication system as claimed in claim 1, wherein said facsimile unit is provided with a hardware dip switch for setting a selection of access inhibition for the security of the user of the facsimile unit.

3. The facsimile communication system as claimed in claim 2, wherein said host computer includes a facsimile interface comprising of a network controller connected to the telephone line, and a modulator/demodulator so that signal transaction takes place between the facsimile unit and the host computer through the facsimile interface.

4. The facsimile communication system as claimed in claim 2, wherein said host computer includes means for setting an operating parameter of said facsimile unit and means for providing a parameter writing procedure.

5. A facsimile communication system operable with a telephone line, the system comprising:

a facsimile unit operable in accordance with a plurality of selectively alterable operating parameters, the facsimile unit having a storage device for storing data corresponding to the operating parameters;

a computer connected to the facsimile unit through the telephone line, the computer having means for reading data stored in the storage device of the facsimile unit over the telephone line and means for altering the data corresponding to the operating parameters stored in the storage device of the facsimile uit over the telephone line.

6. A facsimile communication system as claimed in claim 5, wherein the facsimile unit further comprises a switch having a first switch position and connected so as to inhibit the means for reading from reading data stored in the storage device upon the switch being in the first switch position.

7. A facsimile communication system as claimed in claim 5, wherein the facsimile unit further comprises means for selectively inhibiting the means for reading from reading data stored in the storage device.

8. A facsimile communication system as claimed in claim 5, further comprising a first modem and a first NCU for connecting the facsimile unit to the telephone line and a second modem and a second NCU for connecting the computer to the telephone line.

9. A facsimile communication method fore communication over a telephone line between a host computer and a facsimile unit operable according to preset operating parameters, the method comprising the steps of:

connecting the host computer to the facsimile unit through the telephone line; and

setting an operating parameter of the facsimile unit over the telephone line with the host computer, wherein the step of setting comprises a reading procedure for reading an operating parameter of the facsimile unit and a writing procedure for writing an operating parameter of the facsimile unit.

10. The facsimile communication system as claimed in claim 9, wherein said reading procedure includes steps of sending a software version filed of a non-standard function command signal to the facsimile unit upon detecting a called exchange station identification signal and a non-standard function identification signal indicative of the optional function by a main controller of the host computer, extracting the software version field of the non-standard function setting signal and sending it to the host computer upon detecting the software version field of the non-standard function command signal by a main controller of the facsimile unit, and reading the software version from the software version field, storing it in an internal memory and displaying it on a display unit if the host computer upon detecting the non-standard function setting signal by the host computer.

11. The facsimile communication method as claimed in claim 9, where said step of setting a parameter of the facsimile unit further includes a step of confirming whether the setting has been done correctly.

12. The facsimile communication method as claimed in claim 11, wherein said confirmation step comprises steps of repeating the reading procedure and the writing procedure as to the start address and data and checking the write data and read data in an internal memory of the host computer thereby to confirm the settings in the writing procedure.

13. A facsimile communication method as claimed in claim 9 wherein the facsimile unit has a hardware dip switch for selectively inhibiting altering of an operating function of the facsimile unit.

14. The facsimile communication system as claimed in claim 13, wherein said writing procedure includes data writing by entering a start address and data and storing them in an internal memory when the non-standard function identification signal and the called exchange station identification signal are sent again from the facsimile unit;

sending the start address and data as the non-standard function setting signal to the facsimile unit; and

checking the hardware dip switch for access inhibit selection and storing the data in the facsimile unit if access is enabled.

15. A facsimile communication method for communication over a telephone line between a host computer having an input device and a facsimile unit operable in accordance with a plurality of selectively alterable operating parameters which are stored in a storage device within the facsimile unit, the method comprising the steps of:

connecting the host computer to the facsimile unit through the telephone line; and

reading the plurality of selectively alterable operating parameters of the facsimile unit over the telephone line with the host computer; and

altering at least one operating parameter of the facsimile unit over the telephone line with the input device of the host computer.
