I want to write and receive data from a frequency response analyser. I am connecting to the instrument using a serial connection via a Serial-USB adapter. The manual says it will only transmit when CTS (pin8) is high, and only receive when DCD (pin1) is high, both are listed as input pins. Does anyone know if there is a way to send high signals to these pins when i want to transmit/receive using pySerial?
Thanks.
In the end I used a wire to manually connect the CTS and DCD pins to a pin that constantly outputs a high signal.
