Nate is correct here. The radio has a very tiny buffer in it, and will send an XOFF to the computer when that buffer is full. The computer waits until the radio's BUSY sense goes off, the radio drains the buffer and the radio sends another XON to get things flowing again. It is a selectable option in the radios I've seen, but I can't imagine why you'd turn it off. -- Dan Smith dsmith#danplanet.com, s/#/@/ www.danplanet.com KI4IFW
