Abstract

A data communication equipment has a data communication device, a speech communication device, a selection device for selecting the data communication device or the speech communication device to set the data communication equipment in a data communication mode or a speech communication mode, a detection device for detecting non-data communication mode of a partner station when the data communication equipment is set in the data communication mode, and an output device for outputting a sound on the basis of a sound signal through the communication line.

Claims

1. A data communication equipment for communication via a line, said equipment comprising:

data communication means for communicating data and for receiving data;

speech communication means for communicating speech;

selection means for selecting said data communication means or said speech communication means to set said data communication equipment in a data communication mode or a speech communication mode; and

output means for outputting a sound on the basis of a sound signal received through the line when said equipment is in the data communication mode which has been set by said selection means, said data communication equipment further comprising detection means for detecting a procedure signal for data communication, wherein said output means is stopped when said detection means detects the procedure signal.

2. A data communication equipment according to claim 1, further comprising means for sending a procedure signal for data communication, wherein said output means is disconnected from the line during the transmission of the procedure signal.

3. A data communication equipment for communication via a line, said equipment comprising:

auto-receive means for automatically receiving data;

speech communication means for communicating speech;

mode selection means for selecting said auto-receive means or said speech communication means to set said data communication equipment in an auto-receive mode or a speech communication mode; and

output means for outputting a sound on the basis of a sound signal received through the line when said equipment is in the auto-receive mode which has been set by said mode selection means, said data communication equipment further comprising detection means for detecting a procedure signal for data communication, wherein said output means is stopped when said detection means detects the procedure signal.

4. A data communication equipment according to claim 3, further comprising means for sending a procedure signal for data communication, wherein said output means is disconnected from the line during the transmission of the procedure signal.

5. A data communication equipment for communication via a line, said equipment comprising:

auto-send means for automatically sending data;

speech communication means for communicating speech;

mode selection means for selecting said auto-send means or said speech communication means to set said data communication equipment in an auto-send mode or a speech communication mode; and

output means for outputting a sound on the basis of a sound signal received through the line when said equipmert is in the auto-send mode which has been set by said mode selection means, said data communication equipment further comprising detection means for detecting a procedure signal for data communication, wherein said output means is stopped when said detection means detects the procedure signal.

6. A data communication equipment according to claim 5, further comprising means for transmitting a procedure signal for data communination, wherein said output means is disconnected from the line during the transmission of the procedure signal.
