    When the port is closed, the TXD data line becomes Hi-Z state.

      Hello,

       

      I am using CYUSB232 RDK to check the operation of CY7C65213-32LTXI.

       

      After connecting the device to the USB, its TXD line is High.

      However, once the port is opened / closed by software (ex. TeraTerm Pro), the TXD line becomes indeterminate(Probably Hi-Z state).

      Therefore, incorrect data will be sent to the receiving side.

       

      Is there a way to avoid this situation?

       

      Thanks,

      Shimamura
