Once a device driver has converted an entire journal file into raw device commands, the file of converted commands is passed back to the spooler. The spooler sends these low-level commands to a monitor. A port monitor is a .dll that passes the raw device commands over the network, through a parallel port, or through a serial port to the printer device. Custom port monitors can be installed to support passing device data through other communication ports.
Use the following functions to work with port monitors.
|AddMonitor||Installs a local port monitor and links the configuration, data, and monitor files.|
|DeleteMonitor||Removes a port monitor added by the AddMonitor function.|
|EnumMonitors||Enumerates the port monitors installed on a specified server.|
