  1. We received this BPV4 days ago, but we don’t have USB 2 TTL bus driver, it is said FT232 driver. As a result, we can’t find the COM port. Could you please send me this driver?

    1. Hi Filip,

      Thank you very much. Now I successfully installed the driver and BPv4 is recognized.

      And then I followed the instruction to type “?” But I didn’t see the help information displayed in website. That means I am not connecting? Is it because I need to download firmware prior to any operation?
      Do you have a phone number? Can I talk to you for queries?

      Best wishes,
      Shiyang Gao

      1. Hi Shiyang,
        you need to setup the terminal to 115200 baud, 8bit, no parity, 1 stop bit, no flow control.
        now open the com port that the bus pirate connected to. when you hit enter do you see “HiZ>”

        I’ send you my email, from which we could talk over gtalk.. I’m available from 8:00-17:00 Central European Time (CET)
