## SYMPTOMS

After you install Windows NT version 3.5 on ALR Evolution V-Q/60 and Evolution V-Q/66 computers, the serial ports are not recognized in the Ports option in Control Panel. Windows NT Terminal reports that all serial (COM) ports are in use.

## CAUSE

This problem occurs when Windows NT version 3.5 NTDETECT.COM is not able to read the ALR EISA configuration file for serial port information. This problem does not occur in Windows NT version 3.1.

## RESOLUTION

To resolve this problem, obtain ECU213.ZIP from ALR's bulletin board system (BBS) at (714) 458-6834. This file includes the updated EISA configuration utility (version 213). For additional information, contact ALR Technical Support at (714) 581-6770 or (800) 257-1230.
