I need to control the boot process on an embedded device, so I connected serial console port pins to Putty client, but can't get any output from serial port. I use FTDI TTL-232R-RPi (USB to TTL RS232) cable. I've measured signals on serial console pins, there is -3.15V on RX pin and 0.15V on TX pin. Serial connection settings are correct, COM3, 115200, data bits 8, stop bits 1, parity: none, flow control: none. I used this FTDI cable in the past with another modem, and it worked. What can be the problem?
