Somewhere in the middle of each transfer, the phone line would go dead, and soon afterwards the Mac would put up a dialog box reporting an I/O error. I am using one of the Alpha versions of MacTerminal and have a U.S. Robotics Autodial modem, which is basically similar to the Apple 1200 (read Password) modem. The Vax was very lightly loaded (it usually is at 4 A.M.). When I substituted my 300-baud acoustic modem for the Autodial, I was able to upload all of the files without problem (albeit VERY slowly). I suspect the problem is that MacTerminal sent three "+" characters in the middle of the transfer, thus causing the modem to hang up. Since the 300- baud modem doesn't recognize any special characters, it worked just fine. However, given that the Apple, Hayes, and U.S. Robotics modems all treat the "+++" sequence as a command to the modem, MacTerminal really should take care not to send a "+++" sequence when it can be avoided. When sending files to another computer, it is probably not possible to treat "+++" as a special case. When sending files to another Macintosh (or a Vax pretending to be a Macintosh. . .), MacTerminal should encode "+++" to avoid possible interference from the modem. -- tdn
