Hi,

I know many programs which are monitoring the serial port of a pc (SerialWatcher, PortWatcher, ...). Is this also possible with matlab? I don't want to get a own connection to send/read data, I just want to see what other programs do while they are connected to the serial port.

Would be of great help,
thanks!

Hello Steve,

I found this excellent technical support solution on MathWorks website:
" Is it possible to read from or write to a serial port with MATLAB?"
http://www.mathworks.com/support/solutions/en/data/1-1884B/index.html?product=ML&solution=1-1884B

From the link above:
Here is an example serial session connecting MATLAB to the serial port (COM1) with a baud rate of 4800:
s = serial('COM1');
set(s,'BaudRate',4800);
fopen(s);
fprintf(s,'*IDN?')
out = fscanf(s);
fclose(s)
delete(s)
clear s
