Description

Determines how long an MS-DOS-based application can keep an LPT port open after use. When the time open after use exceeds the value of this entry, the system closes the port and deletes its output. Limiting the time a port can remain open limits the effect of MS-DOS-based applications that use BIOS and do not close the port.
