Thanks for the reply... I added some timing, Pause 10, before and after transmission and it has helped, but still see the problem once in a while, which means I still have the problem. One thing I didn't mention is that I am using an RF link (going from the Pic to a Linx usb chip connected to my PC). It has worked consistenly on a Laptop, but I connected to a desktop PC and it started having problems. I had to develop my own transmit protocal since I can't use or don't want to implement a transceiver solution. Since I went to the desktop I suspect it's a timing issue on the receiving end thru the usb chip to the PC. Has anyone implemented a solution like this???

Thanks again....
