STS top-level constant
String
const STS
Set Transmit State.
STS is used to establish the transmit state in the receiving device. In this state the transmission of data from the device is possible.
The actual initiation of transmission of data is performed by a data communication or input/output interface control procedure which is outside the scope of Standard.
The transmit state is established either by STS appearing in the received data stream or by the operation of an appropriate key on a keyboard.
Implementation
const String STS = '${ESC}S';
