February 28, 2022 - Both should be present but one should be active. I am using MAX3160E transceiver, which allows me to switch between RS232 and RS485. Aim is to connect them to DB9 and control the transceiver to switch. But pin layout of DB9 confuses me. It seems like there is no standard.

June 22, 2020 - First introduced in the 60s, RS-232 is a protocol that defines how the data is transferred, bit by bit from a Data Terminal Equipment (DTE) such as a computer terminal, to Data Communication Equipment (DCE) such as a modem. RS-232 is the common standard used in serial ports. It defines the electrical properties and the timing of signals, as well as the interpretation of signals, and the physical size and pinout configuration of a connector.
