Serial Communications Test (Windows CE 5.0)
The Serial Communications Test verifies the functionality of serial communications on a Microsoft® Windows® CE–based device. The Serial Communications Test evaluates basic functions, conducts stress tests, and tests hardware functionality.
The Serial Communications Test does not appear by default in the Windows CE Test Kit (CETK) window. You can add the test to the CETK with the User-Defined Test Wizard. For more information about the User-Defined Test Wizard, see CETK Tool Operation.
The following table shows the hardware requirements for the Serial Communications Test.
| Requirements | Description |
|---|---|
| Serial null modem cable and available serial ports | Male-to-male null modem cable. A null modem cable differs from a standard serial cable in that it has its RX and TX lines crossed. |
| Two devices | Two Windows CE–based devices. You must connect the devices with the null modem cable. |
The following table shows the software requirements for the Serial Communications Test.
| Requirements | Description |
|---|---|
| Pserial.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 Communications Test, the CETK temporarily copies files to the root directory of the target device. Before running the test, verify that there is at least 0.5 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.
