Legacy Parallel Devices May Not Respond After Resume (242939)
The information in this article applies to:
- Microsoft Windows 98 Second Edition
- Microsoft Windows 98
This article was previously published under Q242939 SYMPTOMS
When you suspend and resume a computer that uses Advanced Configuration and Power Interface (ACPI), legacy (non Plug and Play) parallel devices may stop functioning.
NOTE: Plug and Play printers that you do not turn on before the computer starts may also stop working. This problem affects any device that is connected to a parallel (LPT) port on a computer running Windows 98 and Windows 98 Second Edition.
CAUSE
This issue can occur because Virtual Communications Device (VCOMM) does not attempt to put LPT ports into the D0 power state (full power) when the port is opened; it is assumed to always be powered on. This is a problem, because VCOMM puts the LPT port into the D3 power state (powered off) when you suspend your computer, but does not put it back to D0 after you resume your computer.
