RS232enum | suspect provide Serial but you do not have access

RS232enum is a C++ library typically used in Internet of Things (IoT), Arduino applications. RS232enum has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

RS232enum When you are presented with pins that you suspect provide Serial but you do not have access to the documentation. Connect your Arduino to all of the pins (limited by the number of Ditial pins you have on your board) and this sketch will try every possible pin combination and baud rate to determine RX/TX. It will also try to send wakeup characters to stimulate the line, such as a carriage return or other txpatterns that you add. This code sends data using a custom SoftwareSerial library. For the Parallel scans interpreting the return data would not be reliable. Instead the software just gives a good indication of active lines (parallel scan) and specifically serial lines that respond to wakeup patterns / stimulation (active parallel and active per pin scans). Where reports indicate likely serial the user should then plug up a serial cable and confirm with terminal software on their workstation using the indicated baud rate and wakeup patterns.
