Serial Port Driver Test
The Serial Port Driver Test is a build verification test for the serial port driver. The test assesses whether the driver supports configurable device parameters, such as baud rate and data bits. The test also assesses additional functionality, such as communications (COM) port events, escape functions, and timeouts.
This test does not require additional hardware, such as loopback plugs, null-modem cables, or other devices. The Serial Port Driver Test does not test communications over the serial port. The test verifies that the serial port driver works properly and that the application programming interface (API) for the driver behaves correctly. To test serial communications, run the Serial Communications Test.
The following table shows the hardware requirements for the Serial Port Driver Test.
| Requirements | Description |
|---|---|
| One or more serial ports | Serial ports can be attached as COM1 through COMX. |
The following table shows the software requirements for the Serial Port Driver Test.
| Requirements | Description |
|---|---|
| SerDrvBVT.dll | Test .dll file. |
| Tux.exe | Tux Test Harness, which is required for executing the test. |
| Kato.dll | Kato Logging Engine, which is required for logging test data. |
| Tooltalk.dll | Application required by Tux.exe and Kato.dll. Handles the transport between the target device and the development workstation. |
Note When you run the Serial Port Driver Test, the CETK temporarily copies files to the root directory of the target device. Before running the test, verify that there is at least 0.4 megabytes (MB) of free space in the root directory of the target device. If there is not sufficient space in the root directory of the target device, the test cannot run.
