I am trying to interface Stonex S900A GPS with nVidia TX2 which has ROS melodic installed. The GPS data cable is a DB9 type (RS232). I connected a DB9 to USB converter with the cable and connected it to the USB port of TX2. I intend to use nmea_driver_navsat ros package to read the GPS data. However, when trying to monitor the GPS data on a serial monitor (such as puTTY or CuteCom), I am getting messages in the following format: \
Could it be an issue with the serial driver? When I connect the same GPS with the same cable to another system, I get valid information on the serial monitor. What could be the issue here?
