This is a guide to the serport212 C example project included in the EMAC OE SDK.

This application is a SOM212ES serial combo port configuration tool. It can set the configuration of the serial combo port on a SOM212ES carrier board to mode RS-232, RS-422 or RS-485. It can also get the current serial port configuration, reporting it to the console.

Also included in the project directory is a BASH version of this tool: serport212.sh. It performs the same functions and takes the same command parameters as the C executable version.

The serport212 project builds one executable: serport212.
