I have not experienced a problem with connections dropping once established with my USR Dual Standards. I'm running 9 on a BBS. It is important to be at the latest ROM level. An ATI7 command should show Supervisor date 9/29/89, IOP date 8/8/89, and DSP date 9/18/89. The reason for wanting to be at the latest level is problems with some 2400 bps modems connecting at 2400 bps. It's also helpful to set the S register that controls the duration of the V.32 answer tones (don't have the number handy) to zero. Doing these things takes care of most 2400 bps modem problems. The problem modems that are left seem to have trouble connecting to other V.32 modems as well. Roger Fajman
