Abstract
Disclosed is a facsimile communication device, including: a line voltmeter that measures a voltage of a line used for a facsimile communication; and a hardware processor that: detects a predetermined change in the voltage of the line, in the facsimile communication; and judges whether a facsimile device of an opposite side opens the line or not according to whether the predetermined change is detected.
Claims10
A facsimile communication device, comprising:
- a line voltmeter that measures a voltage of a line used for a facsimile communication;
- and
- a hardware processor that:
- detects a predetermined change in the voltage of the line, in the facsimile communication;
- and
- judges whether a facsimile device of an opposite side opens the line or not according to whether the predetermined change is detected.
A line disconnection judgment method to be executed by a facsimile communication device, comprising:
- repeatedly measuring a voltage of a line used for a facsimile communication;
- detecting a predetermined change in the voltage of the line, in the facsimile communication;
- and
- judging whether a facsimile device of an opposite side opens the line or not according to whether the predetermined change is detected.
A non-transitory recording medium storing a computer readable program causing a facsimile communication device comprising a line voltmeter that measures a voltage of a line used for a facsimile communication, to:
- repeatedly measure the voltage of the line by using the line voltmeter;
- detect a predetermined change in the voltage of the line, in the facsimile communication;
- and
- judge whether a facsimile device of an opposite side opens the line or not according to whether the predetermined change is detected.
