This feature allows you set any serial port into read-only mode. In case of read-only ports you won’t be able to write anything to the port, only data retrieval is possible. Read-only mode can be useful just to read the data and record the real port activity, for example.
To make serial port work in read-only mode in Windows CE or Windows Mobile Pocket PC, please select port in a bundle and then click icon on the main toolbar. To make port work in standard write-read mode, just click the same icon again.
In Windows Mobile Smartphone, please, select port in a bundle, click left soft key, click “4” button and then “2” button:
