How do you find out what serial ports are being used?
You can check what device is using what COM port from the Device Manager. It will be listed under the hidden devices. From the Device Manager, select View – Show Hidden Devices. Now when you expand the (PORTS) COM ports section you will see all of the COM ports listed there.
Do switches have serial ports?
Yes, but probably not the kind the OP was referring to. Its a low-speed Asynchronous? Serial connection which is used for out-of-band management. The main reason for wanting a Synchronous Serial port (e.g. WIC-1T, WIC-1DSU-T1) would be to connect a switch to a Leased Line, Frame Relay, or MPLS (using T1).
What does a serial port look like?
A serial port is male in gender, and has either 9 pins or 25 pins. The shape of the port is slightly D-shaped. A serial computer port may be used for a mouse, external modem, scanner, or other linking software such as for a personal data assistant (PDA). Only very old computers have a 25-pin serial port.
Is RS-232 a COM port?
RS232 is a standard protocol used for serial communication, it is used for connecting computer and its peripheral devices to allow serial data exchange between them. These connectors are known as the DB-9 Connector as a serial port and they are of two type’s Male connector (DTE) & Female connector (DCE).
Which communication configuration is used most commonly by serial ports?
25-pin D-type
The most common type of serial port is a 25-pin D-type connector carrying RS-232 signals. Smaller connectors (e.g., 9-pin D-type) carrying a subset of RS-232 are often used on personal computers.
How do I configure a switch port?
Switch ports can be manually configured with specific duplex and speed settings. Use the duplex interface configuration mode command to manually specify the duplex mode for a switch port. Use the speed interface configuration mode command to manually specify the speed for a switch port.
