This value is used only A bytes available event is generated The settings of the serial communication are selectable using the block panel. RS232_Create_Buffer: Initialize and allocate an input communication buffer. Read data from the serial port and add it to the buffer, but doesn't remove any byte from it. You can communicate with any device or instrument that has a serial interface directly from MATLAB and Simulink with Instrument Control Toolbox. Based on MATLAB supports serial devices including RS-232 when using Instrument Control Toolbox. See RS-232 Serial Communication. RS232_Synch_Binary_Buffer: Looks for data header into the buffer and returns "1" at the output flag when the header is found. Parity, StopBits, All of them have RS232 output, so I use converter cables to USB. An I rewired the null modem cable so that the 34401A's DTR/DSR is instead fed to the CTS/RTS pin of the PC, forced the flow control to be hardware (i.e. Matlab % Matlab code for InLine function sqrt(36) log(exp(1)) MATLAB inline .
