After the hardware connection relationship of explaining PC and HPC, must on this hardware configuration, construct software module to control the running of this hardware configuration.The structure of software module comprises a communication protocol module 401 and at the PC end and receives glossary module 402 as shown in Figure 4; HPC then comprises a communication protocol module 403 and and sends glossary module 404.After when a literal is sent in the HPC tendency to develop, this literal must being cut into many packets through communications protocol module 403, be sent to PC via sending glossary module 404 again; After the utilization of PC end receives glossary module 402 and receives these packets, by communications protocol module 401 packet is untied again, to take out Word message wherein.
After the structure of soft, the hardware of narration, next described is the foundation of the line relation between PC and HPC, with the transmission flow process of Word message.
Fig. 5 is that PC and HPC hold when afterwards linking up the operational flowchart of PC end.When holding (step 501) when beginning to carry out, PC is with the parallel end of first initialization, to reset the buffer zone (step 502) of this parallel end, after the data information of the controlling signal of next tendency to develop being delivered to HPC and test usefulness is sent to parallel end (step 503), send again to link and require signal, notice HPC end PC wants and its binding (step 504) now, then PC reads the back-signalling (step 505) of HPC in parallel end status buffer, can learn the situation of present HPC by this back-signalling, and learn line success or not (step 506,507) in view of the above.If line is unsuccessful, will check the line time whether overtime (step 508), if overtime then line fails (step 509), otherwise will express data information once more and controlling signal is sent to HPC (getting back to step 503).
Correspond to the line requirement of PC, HPC also follows certain procedure and operates the purpose of finishing line.Operating process when Fig. 6 promptly describes HPC and carries out in shaking hands.When the line of receiving PC as HPC requires (step 601), to check earlier whether the user sends requirement so that line interrupts (step 602), if there is not interrupt request then to read in data information and controlling signal (step 603), also allows this moment the user to send interrupt request and stop line (step 604) by pcmcia card.Then HPC will read the line that the PC end sends by pcmcia card and require signal (step 605), and check this line requirement signal whether correct (step 606).If correct line requires signal then to send back-signalling (step 607), to point out the message (step 608) of line success.When carrying out, when sending interrupt request, the user all can make line failure (step 609) when shaking hands.
After setting forth the operating process of PC when carrying out in shaking hands with HPC, the sequential chart among state Fig. 8 is held the back flow process with this and is done further description again.
When PC requires line, after the parallel end of initialization, then send gating signal, so that the BUSY of HPC transfers electronegative potential to, be placed among D0~D7 to allow expressing HPC line control information (data message, controlling signal, line requirement, back-signalling etc.), and output, after this binding control information is stable, HPC sends gating signal again, makes BUSY that signal transfers noble potential to, so that PC can read this literal information.The PC end sends a gating signal once more after reading the binding control information, require HPC to transmit the binding control information once more.
After linking successfully, just the transmission of Word message can have been carried out between PC and the HPC.Fig. 8 and Fig. 9 describe PC end and HPC respectively, the operational flowchart when receiving with transmission mouse signal.
What Fig. 8 described is the operating process of PC end when receiving the mouse signal that HPC sent.When whether the inspection of PC desire has the mouse signal to be sent by HPC, the PC end is regularly carried out the preposition interrupt service routine (step 800) before the read operation, PC will be before reading this literal information, carry out some preposition interrupt service routines earlier, whether keyboard interrupt service routine etc. for example, then detecting parallel end has the mouse signal to have (step 801).Judge then whether parallel end has the mouse signal,, then carry out carry out (step 806) of action that returns to continue other work if there is not the mouse signal.If have mouse signal, PC will read this mouse signal (step 803), and send signal to allow the transmission of next mouse signal, its practice is to transfer the parallel end of PC STB to electronegative potential (step 804).The system messages of then the mouse signal (four parameters) that is received being seen off queuing (step 805), and be shown on the screen of PC.After whole flow performing finished, PC returned (step 806) once more to continue other work.
What Fig. 9 described is the operating process of HPC end when transmitting the mouse signal.When the mouse signal is sent in the HPC tendency to develop to PC (step 900), HPC will check earlier whether the parallel end of PC is busy, its practice is to judge that the parallel end state end BUSY of HPC is electronegative potential (step 901), if not electronegative potential represents that then this parallel end is commonplace, then HPC rests in the waiting status, be electronegative potential to parallel end down, that is to say that this parallel end can receive in this mouse signal, just transmit a mouse signal (step 902) to parallel end mouse signal end.Transfer the parallel end state end of HPC to noble potential (step 903) then, then will check whether still have the mouse signal will receive (step 904), then repeat above-mentioned transmission action if having, and carry out step 901, till all mouse signals all export PC to (step 905) to step 904.
The user need be connected the pcmcia card of HPC when operating disclosed auxiliary mouse input device for computer system with the parallel end of PC, and holds the software module that is written into as shown in Figure 4 in HPC and PC.As user during in the HPC input signal, the information of HPC output has nothing to do with the application software of PC because information by the intrinsic function GetMouseEvent Proc () of Windows system with the system messages formation of seeing off of the four-player parameter of mouse.Because the position of mouse is not simultaneously, the message that is produced is just different, thus system handles HPC sent message after, just can produce mouse function.And when the GetMouseEvent of Windows system Proc () function was seen off the system messages formation with four parameters of mouse, its practice was as described below.The operation message data that HPC transmits are passed to working storage AX, and the relative shift of the X-direction that HPC is transmitted is passed to working storage BX, and the relative shift of the Y direction that HPC is transmitted is passed to working storage CX, and working storage is made as constant 2.GetMouseEvent Proc () is with the system messages formation of seeing off of four parameters of mouse, by Windows inside by oneself then.
The user is at the disclosed auxiliary mouse input device for computer system of operation, and HPC and computer just are being dynamically connected certainly, that is HPC and computer holding in the back links up, and the shown picture of the display of HPC and the display of PC is shown in Figure 10 A and Figure 10 B.After HPC and computer successful connection, the shown picture of the display of HPC and the display of PC is shown in Figure 10 C and Figure 10 D, and the literal among Figure 10 C is when the picture when the PC end carries out the copy editor.
When the user is operating disclosed auxiliary mouse input device for computer system, and after HPC and PC are linked up successfully through shaking hands, and the PC of this moment is being carried out the copy editor, and when the user to be ready carrying out the action of mouse drag, what the display of HPC was shown is the vertical view of a mouse, suppose that mouse on the display is in the position 991, shown in Figure 11 A.And the shown picture of the display of PC is shown in Figure 11 B, and the literal on it is an example, supposes that the position of cursor this moment is 992.
The user needs only on the grid 993 in the upper left corner that constantly contact pen is pressed in the mouse shape at this moment, and then these grid 993 full instructions are black, continue to push down the left button of mouse with the symbol user.This moment is shown just as shown in Figure 11 C on the HPC display.And the shown picture of PC is just as shown in Figure 11 D, and cursor stops flicker.And the user will be pressed in the contact pen in the upper left corner and continue to push down indicator gauge and when moving to position 995, picture shown on the display of HPC is just shown in Figure 11 E by position 991.And on the PC exposing device shown picture shown in Figure 11 F, wherein all anti-white by the literal in the middle of position 992 to the position 996, shown effect when just using mouse to choose passage as the user.
In sum, the present invention serves as a kind of with the mode of connection of HPC as the PC input media, not only utilizes the parallel end of ready-made PC to be engaged in data with pcmcia card and transmits, and the PC end also needn't need various mouse drivers to set mouse again.
