Ready to receive is a status indicating that a device, system, or protocol endpoint is prepared to accept data, input, or energy. It signals that buffers, channels, or interfaces are available and the sender may commence transmission. The exact meaning and mechanism vary by domain, but the core idea is synchronization of data transfer to prevent loss or overflow.

In networking and data communications, readiness is commonly conveyed through flow control or handshakes. For example, TCP uses the receiver’s advertised window to indicate how much data it can accept, with a larger window signaling greater readiness to receive. In serial and hardware interfaces, devices may use signals such as Ready/Not Ready or RTS/CTS to indicate when the receiver is prepared to accept transmission and when the sender should pause. In wireless and radio systems, a receiver may respond with a readiness indication before transmission begins, particularly in half‑duplex or contention-based channels.

In power transfer and charging protocols, a device may negotiate readiness before energy is supplied to prevent charging into an unprepared or incompatible device. In software and user interfaces, a ready-to-receive state may be exposed to callers or users to trigger data input or event handling. The specific implementation—signal lines, messages, or status fields—varies with the technology stack, but the overarching purpose is to coordinate transfers and avoid data loss or resource contention.
