property LastError: Integer read

property LastErrorDesc: string read

---

Establishes a socket to listen for an incoming connection.

procedure Listen(aBacklog: Integer = $7FFFFFFF)

Parameters:

• aBacklog: Desired maximum length of the queue of pending connections. This value may be changed by the transport layer.

---

property Mode: TROSocketMode read

---

Controls TCP packet batching (Nagle's algorithm).
TCP normally batches small logical packets into single larger physical packets (by briefly delaying packets) to fill physical network frames with as much data as possible. This is intended to improve network throughput in terminal emulation environments where mostly keystrokes are being sent across the network. Setting NoDelay to true disables TCP packet batching. Disabling TCP packet batching means that packets are sent regardless of size; this increases the volume of network traffic.
