The characteristics of an open list are:
Anyone can post to the list by addressing mail in the form of listname@domain A term that refers to the subdivisions of the Internet. Domain can mean the major subdivision of which your network is a part, (.com, .edu, .gov, .net, .us, .uk), or it can refer to your part of the network, as in Ipswitch.com. See also Domain Name System..com In DOS systems, the name of a serial communications port In TCP/IP and UDP networks, a port is an endpoint to a logical connection and the way a client program specifies a specific server program on a computer in a network. Some ports have numbers that are preassigned to them by the IANA, and these are known as well-known ports (specified in RFC 1700). Port numbers range from 0 to 65536, but only ports numbers 0 to 1024 are reserved for privileged services and designated as well-known ports. This list of well-known port numbers specifies the port used by the server process as its contact port.. DOS supports four serial ports: COM1, COM2, COM3, and COM4. However, most software uses system interrupts to access the serial ports, and there are only two IRQ lines reserved. This means that the four COM ports share the same two IRQ lines. Typically, COM1 and COM3 use IRQ4, while COM2 and COM4 use IRQ3. So in general, if you have two devices, one of which is attached to COM1 and the other to COM3, you cannot use them simultaneously.port . DOS supports four serial ports: COM1, COM2, COM3, and COM4.
