   - If a button is pressed, the name of the corresponding button (S1, S2, S3) is received in the computer through the RS-232 interface.   - If a button is pressed, the name of the corresponding button (S1, S2, S3) is received in the computer through the RS-232 interface.

-  - The communication between two RS-232 controllers. If a button is pressed, the controller transmits the controller the number of the button. When the number is received the status of a corresponding LED is changed. '1' → green, '2' → yellow, '3' → red. Requires two sets of controllers, but the software is identical in both controllers+  - The communication between two RS-232 controllers.

   - Make a  “teletype” – device, which allows changing text messages between two controllers through RS-232 interface. Use LCD for displaying the messages. On the first row must be seen inserted message and on the second the last received message. For inserting the message a potentiometer and/or buttons may be used.   - Make a  “teletype” – device, which allows changing text messages between two controllers through RS-232 interface.
