I bought it before the Unidisk was released and have never upgraded. Yet, here I type away happily at 2400 baud. Occasionally line noise adds a few characters to what I type and my 'i' key is apt to double strike. But I have had no downloading losses at all. Well, all right, sometimes I have had everything hang, but I am talking all or none. This is not dropping of characters-- this is one of the modems or the campus network getting stuck due to line noise sending special chars or some- thing. I have never had any opportunity to run faster than 2400 baud so it may indeed have problems, but 12 and 2400 baud work fine for me. Sorry, that I have no suggestions for a solution, but even negative information can help isolate the problem. -- Anthony Veale' veale@coma.colorado.edu You're failing to take into Grad.
