Hello Friends
Is there anyway to access USB or any other communication port in our laptop using MATLAB? We can send and receive data on parallel port using MATLAB but can we do it with USB because we don't have parallel port in laptops?
Thanks in Advance

Yes you can. You need the Data Acquisition Toolbox. I use the devices by Measurement Computing Corporation.

Thank You for your response Image Analyst. We can acquire data from all these ports but can we also send data to these ports?

Yes you can. You can read and write (i.e. set or detect) high and low voltages to the pins of the device. You can use it to light up LEDs, detect switch closures, turn on other devices (motors, etc.), digitize analog signals, etc.
