Question about serial port

[mizutani_jun]

Thanks for the reply Jeff.
Yes i already tried with both function vizact.ontimer and vizact.onupdate but still no positive results.
The input/output window still show results as below.

['']
received 0 bytes

Is there any way i can put this command in vizard?

set(s1,'Terminator','CR');
set(s1,'InputBufferSize',1024);

I`m not sure this have connection or this is the reason i cant get the data.
But i dont know how to change this command in vizard so i cant test it out.
I also searched about this two functions on website but seems all the results is just related to matlab.
I really need help about this.
Thanks

MJ
