Access Violation in SPOOLSS when Printing to a Serial Printer (162775)
The information in this article applies to:
- Microsoft Windows NT Workstation 4.0
- Microsoft Windows NT Server 4.0
This article was previously published under Q162775 SYMPTOMS
If a serial port configuration string greater than 20 characters is
specified and that serial port is used by an active printer, Localmon.dll
generates an access violation in Spoolss.exe.
CAUSE
This problem can only occur if the following Registry Key is directly
edited using a Registry Editor:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\
CurrentVersion\Ports\COMx
If a serial port configuration string greater that 20 characters is entered
into this value it will cause Localmon.dll to generate an access violation.
These keys are normally directly configured using Ports in Control Panel.
If this application is used, it is not possible to specify a port
configuration greater than 20 characters. However, it may be necessary to
specify a custom port configuration for some serial handshaking options,
which can require a string longer than 20 characters.
STATUS
Microsoft has confirmed this to be a problem in Windows NT version 4.0.
This problem was corrected in the latest Microsoft Windows NT 4.0 U.S. Service
Pack. For information on obtaining the service pack, query on the following word
