I am trying to use Writefile to send data out a comm port but am having problems achieving a 3 millisecond intercharacter delay 100 percent of the time, which is required to communicate true 9600 baud. I have even tried running my comm send routine in a seperate thread with a time critical priority and it still fails to send out data with proper intercharacter timing. Everything is fine about 99 percent of the time but even when the app is running on a DELL 450 with 128 megs of ram and little running of the machine I have this problem. If there is anything you can think of that would help me correct this problem please email me at [email protected]

Thanks,

George McCollister
