Product

• Print Console, all versions
• Service Shell, all versions

Operating system

Microsoft^® Windows^® 2000

Symptoms

After installing a new card or a new driver, there is no communication with the default COM port:

• COM3 for Print Console
• COM4 for device diagnostics

Cause

Digi^® 4-port cards (Classic4 and AccelePort^® Xp) are configured for the wrong COM ports, usually COM7, COM8, COM9, or COM10 instead of COM3, COM4, COM5, or COM6. There are two possible causes for this problem:

• An old card was not uninstalled before replacing it with a newer type of card
• An old driver was not uninstalled before upgrading to a newer driver (updating the driver through the GUI does not cause this problem)

Solution

The “phantom” ports must be uninstalled. Follow the procedure in Re-establishing Communication With Default COM Ports After Installing a New Driver or Card.
