Time-out Error Messages when Printing in Windows NT with Service Pack 5 and above Time-out Error Messages when Printing in Windows NT with Service Pack 5 and above Symptom: Event Viewer Error
Cause: The driver is doing an immediate flush of the write buffer for the application to timeout.
Solutions: You must install driver v2.6.4 or newer and change the port setting to WriteTimeoutDrain=1. This must be done for each Digi port which you wish to use for printing.
The latest driver can be downloaded from ftp://ftp.digi.com/support/drivers/winnt.
After the latest driver has been installed, start the registry editor by typing start regedt32 from the command prompt. Select the following: HKEY_LOCAL_ MACHINE on Local Machine, System, CurrentControlSet, Services, ntxem#, Parameters, Line#, Concentrator#, Port#.
NOTE: The "ntxem#" above may be different for different adapters. Other values are ntxall#, ntepc#, ntcx#, or dgapci#.
Add the following: WriteTimeoutDrain:REG_DWORD: (Default=0)
Enabling this prevents the driver from doing an immediate flush of the write buffer on an application timeout. The entry is not initially set in the registry and must be manually edited. Set the entry to: WriteTimeoutDrain=1 to enable. This is done on a per port basis and must be done for each Digi port which you wish to use for printing.
CAUTION: Any mistakes made in editing the registry may have disasterous results requiring you to boot to a different Control Set or to reload Windows NT.
