Which five criteria comprise a modems port settings?

A modem's port settings typically comprise the following five criteria: the port number, which specifies the communication endpoint; the protocol, indicating the type of communication (e.g., TCP, UDP); the baud rate, determining the speed of data transmission; data bits, which define the number of bits in each data packet; and parity, which is used for error checking in data transmission. These settings ensure proper communication between devices.
