OK! I think there might be a problem with my PC cable. With a standard 25 pin to 9 pin adapter and a gender changer on my M100 cable, I'm getting some output, but there may be some other issues with the drive or cable.
I will paste my results below. -------------------------------------------------------------------------------- `ready' without a disk: -------------------------------------------------------------------------------- % VERBOSE=9 ./pdd.sh ready get_tpdd_port() Using port "/dev/ttyUSB0" open_com() set_stty() speed 19200 baud;
