rs232 transmitter program download
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.
Bob.
