Application using the serial port
We are writing an application which takes data from the serial port, more accurately from the serial port windows API. Data will be presented to the port sporadically and we intend capturing the data, but are unsure about what the best way to do this is? The data will arrive sporadically so I do not think polling
the port would be the best. Would it be better to wait for a character and then process the data character by character? Any thoughts? |

Re: Application using the serial port
your program will want to create another thread then have that thread wait for incomming data. If you read the description about serial ports in MSDN for CreateFile() function it will give you information about how to do that. Scroll down the page near the bottom to the section heading Communications Resources then follow the Communications link.
