The invention provides a control information format construction used in image information transmission in a system combining a facsimile device and a computer, having: a head code of one byte for showing start of the control information; a control code of one byte located at just after the head code, including an operation mode control information, a manuscript mode control information, an end control information, and a response control information for error, for showing the kind of control; and a control end code of two bytes located at just after the control code, for showing end of the control information.

Control information format construction used in transmitting image

The invention provides a computer connection circuit in a facsimile, comprising: control and memory unit including CPU(Central Processing Unit)(11a), RAM(Random Access Memory)(11c), and ROM(Read Only Memory)(11b) for controlling a general operation control of the facsimile; address decoder 12 connected to the control and memory unit through an address bus, for selecting and enabling an output terminal according to an input address; a modem 31 connected to the control and memory unit through a date bus and connected to communication lines, in which is driven by a first chip selection signal of the address decoder 12 and requires an interrupt to the control and memory unit in sending/receiving image information; and an UART51(Universal Asynchronous Receiver & Transmitter) connected to the control and memory unit and to RS232C interface means of the computer, in which requites an interrupt to the control and memory unit in sending/receiving image and character information to/from the computer and is driven by a second chip selection signal of the address decoding decoder 12.
