SerialWrite Mex

SerialWrite is written in C and allows you to write to a serial or com port.

Description

SerialWrite is written in C and allows you to write to a serial port without using the Matlab SERIAL interface. The reason for this is that Matlab's SERIAL often crashes/"Times out". The code is short and easy to understand for future modifications, or it can be used as is.

serial_write('open', 'COM40', 57600);
serial_write('write', 'Hello');
serial_write('write_line', ', World'); % Adds the \r\n
serial_write('close');

• MATLAB release: MATLAB 7.5 (R2007b)
• Other requirements: Windows

Thank you for this code.
I was looking for an alternative to the "serial" given by Matlab because it is too slow/cannot compile to mex.
Your code is faster and indeed easy to understand.
Yet being new to Matlab I don't understand where does the WriteFile function come from. Likewise, is there a ReadFile function one could use in the same way ?

WriteFile is part of the Windows API.

Check out ReadFile here: http://msdn.microsoft.com/en-us/library/aa365467(VS.85).aspx

I'm normally program Linux or Mac, so I don't know this stuff well (I learned about WriteFile when I wrote SerialWrite)

Thank you.
This will be very helpful to make s-function
