     A couple things to check with ADT are ...

1. The PC part needs to run under DOS, not Win95 or a Win95 DOS window.

2. The baud rate on the PC needs to be set to the same speed used on the Apple
II (or Laser 128).


     Even with speed being slightly off, transfers should work at 2400 baud. If
there is some way to set baud rate directly on the '128-- like a control
panel-- you might try that.
