Can I know the method of feeding Matlab code output to a hardware circuit through RS232?

use serial() to indicate the properties of the port you want to communicate with. Use fopen() to activate the port. Use fprintf or fwrite to the port to send data. To receive data use fgetl or fgets or fscanf or fread

Actually the output data to be fed into the hardware is in the binary form of 256*256 matrix from matlab platform.Is it possible to fed that large bulky data through RS232 connector?

[Walter Roberson]

Yes, you can fwrite() or fprintf() to a serial port.

For receiving larger input you would want to adjust the InputBufferSize

For sending larger data you can set the OutputBufferSize

Thanks for the answer. But actually How can I check if the matlab binary data from the transmission PC has been transmitted through the hardware to the receiver PC? Are there commands for the receiver end?

[Walter Roberson]

Insufficient information. Is the receiver running MATLAB?

If you are doing bulk transfer of data, you should consider using PPP or SLIP over the serial line to provide an IP interface which you can then use to scp or ftp files around. Or you should consider using the Kermit package.

[Mangai s]

Thank you.Yes the received binary data must be displayed in matlab at the receiver PC. The data must be transmitted and received serially through RS232 cable on both the ends.

[Walter Roberson]

Designing reliable communications yourself just isn't worth the effort. I recommend you set up PPP or Kermit between the hosts. See https://mikebeach.org/2012/08/30/installing-and-configuring-a-ppp-null-modem-connection-on-windows-7/
