Serial ports typically use a DE-9 (sometimes mistakenly called "DB-9") connector. This is a connector with 9 male pins protruding from the computer. They are part of a group of connectors called "D-sub" connectors, both because of their shape, resembling a "D", and their size which was rather small at the time they were introduced.
RS-232 serial ports are far slower than USB ports. With very few exceptions, devices that use USB ports would be impractical to use on a serial port.
RS232 is a communications protocol for electronic devices to exchange information
Most modern laptops lack any sort of "legacy" ports such as serial ports, let alone them having two. Some older laptops did have multiple serial ports, but there's little point in recommending one because there's no guarantee you could find one. There are options for adding serial ports to a laptop, such as a USB to serial adapter, or a PC card with additional serial ports.
Also known as a serial cable; typically with 9 or 25 pin D-sub connectors.
If you are referring to the RS232 jack, it was mostly used to connect modems to the computer. Today it is sometimes still used to configure beamers or routers.
Yes, you can get a USB to RS232 converter (aka USB to Serial).
RS232 means "Recommended standard no. 232", EIA standard for serial communication Thirumalesha.....
Data Terminal Equipment (Serial)
Serial connector term is used for an interface connector on which the protocol of data transfer is serial type. Serial data transfer means one electrical connection or signal for data transfer (one bit at a time from transmitter to receiver) at specific speed (bits per second). Note that on the connector actually there may be more than one electrical connections for signals other than serial data, which include clock and power in some cases, or control signals. Serial data itself may be electrically sent in differential form in which case serial data itself needs two wires (positive and negative). Common examples of serial connectors include serial port (RS232) and USB.
Yes on a modern computer you will need a USB to 9 pin RS232 converter or previously use the LPT parallel port.
There generally r 2 com ports, com1 and com2. They are RS232 ports which r serial ports.one way to communicate between 2 PCs is to use a software called hyperterminal..its there in evry computer.( accessories-> communication tools). if not u can also install it. u can find more information on it online..in case..1> u can either use an RS232 to IR converter device connected to the respective ports of both the comps to communicate.u'l be usin IR communication in dis case.2> u can connect a cable between these two ports of both the comps( female-female...as RS232 is a male port).but ure comps wud need to b in close proximity for a physical connection like dis. u can get back to me for any further clarification on the same.
