Note:
In DTE mode, the signals CD, DSR, and CTS are tied to +12 volts (through a resistor) to
indicate that the QSDI port is always ready to transmit and receive data.

In DCE mode, the signals DTR, and RTS are tied to +12 volts (through a resistor) to
indicate that the QSDI port is always ready to transmit and receive data.
