Described Serial Port Line 402 can adopt a two female Serial Port Line, is used to connect network computer first serial 101 and second serial 102.Why be called transition element, be because it can realize the transfer between network computer first serial 101 and the GPIO serial ports 103, thereby solve data write problem in the network computer first serial 101.By adopting Serial Port Line 402 that network computer first serial 101 and second serial 102 are coupled together, by network computer second serial 102, can be from reading the data that network computer first serial 101 sends.Simultaneously our data of the IC-card 300 that also GPIO serial ports 103 can be sent are written to first serial 101 by network computer second serial 102.
After reading the data of network computer first serial 101, in order to realize the mapping of network computer incorporating IC card GPIO serial ports 103, need set up data channel between GPIO serial ports 103 and network computer second serial 102, the finger daemon unit 403 of apparatus of the present invention is used to realize this function.
See also Fig. 3 and Fig. 4,, can realize the mapping of network computer GPIO serial ports 103 and network computer second serial 102 by finger daemon unit 403.Described finger daemon unit 403 comprises control device 431, first device 432, data forwarding device 433 and second device 434; Described control device 431 connects first device 432, data forwarding device 433 and second devices 434, is used to empty network computer first serial 101 and second serial 102, the IC-card 300 that resets, resolves to automatically reset and reply, control first device 432 and second device 434 reads and writes data and data forwarding device 433 is transmitted data work; Described first device 432 is used to read the data of GPIO serial ports 103 and writes data to GPIO serial ports 103; Described second device 434 is used to read the data of network computer second serial 102 and writes data to second serial 102; Described data forwarding device 433 is used to transmit the data channel between first device 432 and second device 434.Certainly, described reading with the work that writes data to GPIO serial ports 103 also can be realized by different devices respectively.
When network computer 100 detects the request of landing WBT, start working in finger daemon unit 403, implementation step D1 at first, and control device 431 empties network computer first serial 101 and second serial 102; Control device 431 is implemented the step D2 that IC-card resets subsequently; Step D3 resolves ATR (automatically reset and reply); Next enter step D4, second device 434 is read network computer second serial 102 under the control of control device 431; When network computer second serial 102 had data, second device, 434 steps performed D5 read a frame ordering frame; Execution in step D6 then, data forwarding device 433 forward it to first device, 432, the first devices 432 and give GPIO serial ports 103 with the data forwarding of reading under the control of control device 431.Step D7 reads GPIO serial ports 103; When 102GPIO serial ports 103 had data, first device, 432 steps performed D8 read a frame ordering frame; Execution in step D9 then, data forwarding device 433 forward it to second device, 434, the second devices 434 and give network computer second serial 102 with the data forwarding of reading under the control of control device 431.
As mentioned above, by RDP map unit 401, Serial Port Line 402 and finger daemon unit 403, can realize the mapping of GPIO serial ports 103 under WBT.When the application under WBT when server serial ports 201 writes data under WBT, can be written to network computer first serial 101 by 201 mappings of server serial ports under the WBT, simultaneously, because network computer first serial 101 interconnects mutually with second serial 102, data and then be written to second serial 102, at this moment, can be by reading network computer second serial 102, obtain this data, and be transmitted to GPIO serial ports 103; Data for 300 generations of IC-card module, can read and be transmitted to network computer second serial 102, because first serial 101 interconnects mutually with second serial 102, data will be written to the first serial 101 of network computer, and then, be mapped to server serial ports 201 under the WBT by RDP, realize the mapping of server serial ports 201 under the network computer IC card module GPIO serial ports 103 to WBT.
