Try using a High speed hardware handshaking cable, I have one and I can get up to 19.2, but if I go any higher than that I have trouble with sending and receiving when I'm uploading and downloading but I am thinking of buying a new cable for my computer. I use an Apple IIGS with a rom3. and Proterm with a 28.8 USR Sportster, try that and see what happens. BradBuchner@delphi.com
