In RS-232, user data is sent as a time-series of bits. Both synchronous and asynchronous transmissions are supported by the standard. In addition to the data circuits, the standard defines a number of control circuits used to manage the connection between the DTE and DCE. Each data or control circuit only operates in one direction, that is, signaling from a DTE to the attached DCE o… WebDec 12, 2012 · When the DTE device is ready to receive data: It sets its RTS signal to a marked state all 1s to indicate to the DCE that it can transmit data. If the DTE is not able to receive data—because of buffer conditions, for example—it sets the RTS signal to all 0s. It sets its CTS signal to a marked state to indicate to the DTE that it can transmit data.
