Hi, If the gap is only about 5ms and then the transfer continues it is probably just due to the windows operating system interupting your program to do something else that its creator considered more important. Is a 5ms pause a problem to you? This sort of thing happens all the time under Windows.
Serial port handling under Windows is a low priority task as far as the operating system is concerned so many other system tasks are able to interrupt it. I do not think there is actually anything wrong with what you have done, it may be possible to change the priority of your program so that it has first call on the system resources if this is a time critical application, I know this is possible but personally I have never actually done it yet so cannot advise you as how to do this. I do not believe this is due to any system interrupt handlers not working correctly. Hi, I am replying you after my testing. Fairplay Golf Cart Service Manual more.
Actually the time between two bytes are getting varied and not is being a constant time gap. What i observed is that it varies from 3 milliseconds to 120 milliseconds. What i am worrying is that i can tolerate a time delay of 5 milliseconds in my application.but it is varying up to the max of 120 milliseconds. I have a doubt that will it be solve when i run this application in pure DOS rather than running in windows or in command prompt of windows OS. Whats ur idea? Hi Bob, I worked today with the tolerance of such delay(120 ms).As your advise i planned to try it in a machine running in a DOS environment tomorow.
I have one more doubt is there any possibilty to set the priority of the application while running in windows.I found there is an facility in Windows to set the priority manually from task manager window.I planned to run my test by setting high priority tomorrow and let u know.If it works fine, i have to set the priority from the C code in my application rather than changing it in the task manager window since the user has to set the priority when ever he close and reopen the application.Because the priority will be reset once the application gets closed.
