Forgot to mention that I am using cygwin on Windows Computer. The device is a real hardware whose serial port is where I am trying to send some data & read the response back. So what I do is send commands from Hyper-terminal to the hardware using the serial port. For the command that I send, I get some response back. This is the why I am aware of what response I am looking for. Now I go back into cygwin perl environment & using Device::SerialPort module I attempt to send the same command. When i try reading the response, I see those scribbled characters. I have my framework developed in perl & communicating to serial port is just a small part of it. Hence the reason I am trying to incorporate perl's Device::SerialPort into my perl framework. Are you aware of any other method to open up Serial Port in perl & send commands ? Please let me know, if you have any more questions & thanks for your help.
