Given that you are running at 300 baud, i would like to see what happens when you change 1.300 to 1.3000000

    change 1.300 to 1.3000000

    Since I don't see any timeouts set up, I doubt that trying to read 3 megabytes instead of 300 bytes from the port would make a difference... the OP's expected result is somewhere around 200 bytes long.

      I didnt see where it was said the perl program was killed either, and so the loop of 300 must have terminated. So i wondered if there were non printing characters being returned while the device was processing. A larger "window" might show results after some period of time.
