Data Framing and Transmission.

I want to develop a model which shall create a data frame based on a said protocol, and shall be able to transmit that over the UART port of the target.

Currently I am trying to create a 40Byte buffer to contain the frame and then transmit the same over COM1 port of the PC, i byte at a time.

Any suggestions on how to improve on the same?

With the multiple contradictory tags you used, I am not certain now whether this is for MATLAB directly or for Simulink or for code to be embedded with a processor.

This is for a code to be embedded with a processor, but i need to prove the concept in simulink before the code is integrated.

I don't know if this will help:

So you would create a signal that held the bytes and put them through the serial send block. By definition serial ports send one byte at a time.
