This question is more complicated than it appears. At the most superficial level the answer is Yes and No. That is, yes, there is a Linux program called "minicom" which is equivalent to Hyper Terminal. No, minicom won't send text strings through a USB port (and neither will Hyper Terminal). Furthermore, there is no standard for sending text strings to a USB device. USB isn't like an old-fashioned serial port. Every manufacturer does it in a different way, and you didn't say anything about how the Allmotion device does it.
