Hi, I am using a usb dongle to communicate with my robocar. Hence, I write the the code as follow: code:
device=instrfind;
but the answer I obtained is empty array. May I know what is the problem? By the way, I can communicate my robocar with hyper terminal. Thanks

By referring to this thread, i obtained the following result:
s=instrhwinfo('Serial')
s =
AvailableSerialPorts: {2x1 cell}
JarFileVersion: 'Version 2.9.0'
ObjectConstructorName: {2x1 cell}
SerialPorts: {2x1 cell}
s.AvailableSerialPorts
ans =
'COM5'
'COM6'
This should be the solution for my problem.
