Abstract

The facsimile control method comprises the steps of: transmitting a print standby signal to a computer when a print request signal is received from a computer; receiving a print mode during a prescribed time and transmitting a mode sensing signal; storing data received from the computer in a first-in first-out (FIFO) buffer; checking whether data or a command is received; and decoding the data stored in the FIFO buffer, storing the decoded data in a line buffer and generating the data to an image recorder when the line buffer is full. The method serves a user's convenience.

Computer main control means connected to the A facsimile control method for printing image data in a system connected to a computer, comprising: a first step of transmitting a print wait signal to a computer when a print request signal is received from a computer side of a facsimile decimation program; A second step of receiving a mode and transmitting a mode recognition signal to the computer; a third step of enabling a data receiving interrupt (INTRX) to store data received from the computer in a FIFO; data or command for a new set time A fourth step of determining whether or not to receive the data; if the data is received in the fourth step, decoding the data stored in the FIFO, moving the data to the line buffer, and outputting the data to the image recording unit whenever the line buffer is full. Kerr received in step 5 and step 4 Characterized in that Degas is carried out by a sixth step to terminate processing if the end of file signal or abort signal.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic diagram of hardware configuration data of a computer-facsimile connection system to which the present invention is applied. In FIG. 10, a facsimile apparatus, 11 a facsimile control unit, 12 an image scanning unit, 13 a modem and a network control unit, 14 Is serial connection, 15 is image recorder, 16 is RS232C connection, 20 is computer (PC), 21 is main computer part, 22 is main memory part, 23 is hard disk, 24 is keyboard, 25 is monitor, 26 is RS232C 30 is a connection part, respectively.

As shown in the figure, a PC-FAX system to which the present invention is applied is connected to a public communication network for transmission and reception of an external facsimile, and a modem and a quantity having a relay for selecting and switching facsimile mode and telephone mode therein. A control unit 13, an image scanning unit 12 for reading an image of a set original, a facsimile control unit 11 connected to the modem and network control data scanning unit and controlling input and output of image data; An image recording unit 15 for printing image data or ASCII (ASCII) data connected to the facsimile control means; a serial contact portion 14 and an RS232C connection portion 16 connected to the facsimile control unit and connecting the facsimile to a PC; It is configured to connect the facsimile device 10 having a) to a PC 20 that is already widely used and used. One RS232C connection section 26, a main memory section 22 composed of ROM and RAM, a hard disk 23 as auxiliary memory, a keyboard 24 and a monitor 25 as input / output devices, and the RS232C connection section described above. And a computer main control unit 21 connected to a hard disk, a keyboard, a monitor, and a main memory unit to perform overall control, and it is preferable to configure a PC of an IBM (registered trademark) compatible model.

2 is a flowchart of a main program execution of the present invention applied and executed in the system as shown in FIG.

When a print request signal is received from the PC (42) during program execution (41) during fax standby, a print wait signal is transmitted to the computer side (43) and the time (time 1) of the timer is set (44).

Then, the print mode is received from the computer side for a predetermined time (time 1) (45, 46), if not received, transmits the abbot signal to the computer side (56) to terminate the execution, and prints within the set time. When a mode is received, a mode recognition signal is sent to the computer (47), the data receive interrupt (INTRX) is enabled to receive data from the computer, so that the received data is stored in the FIFO (48), and the timer Set a new one (49).

Check whether or not data is received from the computer for a set time (time 2) (50, 52) .If data is received, the data stored in the data FIFO is decoded and transferred to the line buffer (53). When is filled up, the contents are transmitted to the image recording unit (thermal recording apparatus) (54, 55), and are repeated again from the above-described two-time process 49.

If no signal is received during the set time (time 2) (50), the aboard signal is transmitted to the computer side (56), and if the command signal is received (51), the received command is specifically Check whether the end of page, end of file, or abort signal (57, 59, 60) is the end of page signal that the next page is present (57) and then send the end of page recognition signal to the computer (58). After receiving the print mode again from the fixed time set 44 again, the next page is received and printed. If the file end signal is received (59), the file end recognition signal is transmitted to the computer side (62). If the received comment is not the end-of-page signal or the end-of-file signal, it is an abort signal (60). If it is an abort signal received from the computer side, it is terminated immediately. ) Will be terminated.

Therefore, referring to the data flow in the present invention, when data received from the computer side is stored in the FIFO by the data reception interrupt INTRX, the data is fetched from the FIFO by the main program, decoded, and then transferred to the line buffer. Then, in the process of executing the main program, it is output to the image recording unit and printed.

Accordingly, the present invention as described above has the effect of improving the economical and convenience of use by enabling the printing of the stored image on the computer side without any additional device in the computer-facsimile connection system.
