Abstract

A computer accessory is disclosed that includes a module. The computer accessory comprises a module having an input port and an output port and a microprocessor circuit that generates an output signal in keyboard character code at the output port that is of selected correspondence to an input signal in keyboard character code received at the input port. Coupling components enable insertion of the module in a data transmission path between a selected keyboard and an associated computer system.

Claims

1. A computer accessory for coupling to an associated computer system having an input device, and for receiving input signals in a print code from a separate source, comprising:

a module having a computer input port, a source input port and an output port;

circuit means for generating selectively an output signal in keyboard character code at said output port, said output signal corresponding to an input signal in print code received from the separate source at said source input port or corresponding alternatively to a computer input signal received from the input device;

means for converting said input signal in print code to said output signal in keyboard code;

coupling means for enabling connection of said module in a data transmission path between the input device and said associated computer system, the input device being coupled to said computer input port, said coupling means for enabling alternatively said computer input device to send computer input signals through said accessory via said path to said output port;

said coupling means for enabling alternatively converted input signals to be sent via said path to said output port;

memory means responsive to computer input signals from said computer input device for storing a copy of said computer input signals therein as said input signals are being supplied to said output port; and

memory read-out means for supplying subsequently the stored copy of said computer input signals from said memory means via said data transmission path to said output port.

2. A device as recited in claim 1, further comprising:

said input device being a keyboard;

keyboard coupling means for coupling a keyboard signal from the keyboard to the input port; and

computer coupling means for coupling the output signal from the output port to a selected computer input port.

3. A device as recited in claim 2, further comprising:

keyboard connector means for enabling connection of a selected keyboard cable plug to the module; and

computer connector means for enabling connection of the module to a selected computer system in place of the keyboard cable plug.

4. A device as recited in claim 1, further comprising:

said circuit means for generating said output signal in keyboard character code that is of correspondence to input signals in ASCII code received from the separate source at said source input port.

5. A device as recited in claim 4, further comprising:

second input coupling means for coupling a second input signal in ASCII code from a selected source to the second input port.

6. A device as recited in claim 5, further comprising:

second input connector means for enabling connection of a selected printer cable to the module.

7. A device as recited in claim 4, further comprising:

a third input port; and

third circuit means for generating a third output signal in keyboard character code that is of selected correspondence to a third input signal in Morse code or any other suitable "on-off" code received from a separate source at the third input port.

8. A device as recited in claim 7, further comprising:

third input coupling means for coupling a third input signal in Morse code or any other suitable "on-off" code from a selected source to the third input port.

9. A device as recited in claim 8, further comprising:

third input connector means for enabling connection of a selected miniature phono plug to the module.

10. A device as recited in claim 1, wherein the circuit means comprises:

micro-computer circuit means coupled to the input port for sensing a predetermined input keystroke pattern and generating a corresponding output keystroke pattern.

11. A device as recited in claim 1, wherein said circuit means further comprises:

direct coupling means for selectively coupling an input signal received at one of said input ports to the output port; and

disabling means for selectively disabling the direct coupling means to enable transmission of said output signal to said output port.

12. A device as recited in claim 10, further comprising:

programming means for enabling the generation of an output keystroke pattern of desired correspondence to an input signal in keyboard character code.

13. A device as recited in claim 10, further comprising:

programming means for enabling the generation of an output keystroke pattern of desired correspondence to an input signal in ASCII code.

14. A device as recited in claim 10, further comprising:

programming means for enabling the generation of an output keystroke pattern of desired correspondence to an input signal in Morse code or any other suitable "on-off" code.

15. A device as recited in claim 1, wherein said input signal is an on/off signal.

16. A device as recited in claim 1, wherein said input signal is an on/off signal.

17. A device as recited in claim 8, wherein said input signal is an on/off signal.

18. A device as recited in claim 9, wherein said input signal is an on/off signal.
