You can use an IoT card for UART -\> RS232.  
Also, the 15 pin connector provided 2 wire UART at 3.3V TTL.  
What’s your use case?

I’d like to connect with a mangoh yellow and other electronic devices via RS-232 and give them a set signal, but I don’t know what api I’m going to use to create an application.
