Hi guys, I'm trying to use a usb to serial cable with matlab

s = serial('/dev/tty.usbserial');
fopen(s)

the above works fine. However, when I try to close to the port with

fclose(s)

Matlab crashes. Anyone have similar problems, and find a solution?

Hi Scott,

We did not see that in testing for 9b. It would be best to call into
support your details but we would need the following to reproduce the
problem.

Which version of MATLAB?
32 bit or 64 bit MAC OS X?
What brand/model of USB adaptor are you using?
- links to the product and driver are a plus.
