![]() NCOM-11X supports several operation modes, including Driver mode, RFC2217 Server/Client mode, Pair Connection mode, TCP Server/Client mode and UDP mode. The virtual serial port redirection uses the protocol known as RFC2217. NCOM-11X serves as a transparent virtual serial port without limitations on operating systems and distances. ![]() Applications include accessing a faraway device for functions such as remote control and data transmission. The serial device server can map TCP/IP connections and UDP broadcasts to a virtual serial port. It is designed to control your serial devices located virtually anywhere through a TCP/IP or UDP/IP network connection. COM port numbers should only be used with COM names.īy default, the combined operation of the class installer for the Ports device setup class and the Serial function driver configure a device as a COM port.įor information about how the Ports class installer and Serial function driver create a COM port device interface for a COM port, see External naming of COM ports.NCOM-11X is a network-based serial device server. If you use a COM name, you must obtain the COM port number from the COM port database. To ensure compatibility with most applications that access COM ports, you should assign a symbolic link name that uses the standard naming convention COM, where is the COM port number (for example, COM1). You operate the COM port by using the 16550 UART-compatible interface that is defined in Ntddser.h. The GUID for this class is GUID_DEVINTERFACE_COMPORT, which is defined in Ntddser.h. ![]() You access the COM port through an instance of the COM port device interface class. A COM port is a type of serial port that complies with the following additional requirements:
