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.

Opening, Building and Uploading the Project Files
For information on opening the project from within Eclipse, please see Importing the EMAC OE SDK Projects with Eclipse. Then, follow Using the EMAC OE SDK Projects with Eclipse for information on how to build, upload and execute the example.
Alternatively, the Makefile can be used with the make command from the commandline to build and upload the example. For more information on this method, please see Using EMAC OE SDK Example Projects.
Usage and Behavior
serport212 gets or sets the configuration of the serial combo port on a SOM212ES carrier board.
Hardware Requirements
The serport212 C example project must be run on a SOM212ES carrier board.
Using serport212
./serport212 [-s CONFIG]
Where CONFIG is a valid serial port configuration specification: 232, 422 or 485
Options:
| <no options> | Get serial port configuration |
| (--set) -s [232, 422 or 485] | Set serial port configuration |
| (--help) -h | Print help message |
| (--version) -v | Print version |
Usage Example. Setting the Configuration of the SOM212ES Serial Combo Port
som9g45:/tmp# ./serport212 -s 232
...the configuration of the SOM212ES serial combo port is now set to RS-232 mode.
Usage Example. Getting the Configuration of the SOM212ES Serial Combo Port
som9g45:/tmp# ./serport212
RS-232
...serport212 reports that the SOM212ES serial combo port is set to RS-232 mode.
Summary
The serport212 application is a SOM212ES serial combo port configuration tool. It sets or gets the configuration of the serial combo port on a SOM212ES carrier board.
