Using c # and.net programming, serial port communication often need to confirm via a serial port sent right data, in order to find send bugs in your code, I am currently using is corresponding to the computer's USB port with a USB232 drive, and then take short drive send and return the feet, the data in the same USB port to return, and then to monitor the serial port the data returned, because often don't have USB232 drive, so want to find a more simple way,
Have no drive, "pure software method, it can monitor to the serial port to send data? I send data by comA, for example, to "map" to comB back by software, and then with a third party like sscom debugging tools, to monitor data is correct, thank you.

1. If you have already connected devices, because of a serial port must be exclusive to open, so the use of virtual serial port tools VSPD pro the split of the entity split into two virtual serial port, serial port connect virtual serial port 1, your software you debuge debugging by virtual serial port 2
2. If there is no equipment, just pure debugging, so use virtual serial ports directly VSPD pro virtual virtual string, a pair of virtual serial port 1 input the output of the corresponding virtual serial port 2, virtual serial port 1 is your software, you debuge debugging by virtual serial port 2

3 accessport, Bus Hound this tool based on pci Bus filter drivers, monitoring data can be directly

Just tried, in the connected under the condition of the equipment, the physical serial port COM5 split into two virtual serial port COM1, COM2, software data sent via COM1, sscom sent via COM2 received data, but the connection entity COM5 equipment didn't receive the data, what reason be? thank you

Download "serial debugging assistant" virtual serial port, and use your software to send, serial debugging assistant, can want to play
