RS-232

Serial communication with RS-232 protocols

RS-232 is a mature point-to-point protocol for serial communication. Use the RS-232 blocks to communicate with other devices by using the serial ports built into the target computer. For detailed information about the target computer serial ports, see the manufacturer documentation.

See RS-232 Serial Communication.
