Express 3000 not detected.
The Express 3000 may not be detected for several reasons.
1. Verify the following:
a. The Express 3000 is powered on.
b. No other applications are running that could be using the
COM port to which the Express 3000 is attached.

COM port. Be sure to check the Windows 95/98 Taskbar for
any suspended applications (such as HyperTerminal) that
may be using the COM port. If any applications are mini-
mized, they must be closed
before
starting the ADTRAN
Express Configuration program.
