Hi,

I am running a serial communications application which should effectively run 24/7. I am using a timer tick event to send messages to the serial port, however i am finding that after the app has been running for 15-30mins, the messages are not being sent at the correct interval of 150ms. I have got enough time to process data coming into the serial port.

Does anyone have anyone have any idea why this might be?

Regards,
nisha
