About IP Messenger 关于飞鸽传书
This is a Send/Receive message service using the TCP/UDP Port. 它是基于 TCP/IP 端口的收发信息服务。 Characteristics 特点 IP Messenger can be installed in any OS if TCP/IP is used on your machine. 飞鸽传书可以安装在任一使用 TCP/IP 协议的的操作系统上。 Dynamic member recognition can be done within your network or specified network. 在网络中完成了动态用户识别机制。 You can exchange messages between all IPMsg members. 所有飞鸽用户之间可以相互交换信息。 Function description 功能描述 Use TCP/UDP port(default:2425). See the following descriptions 使用 TCP/UDP 端口（默认端口：2425）。见下述描述 (Message Send/Receive: UDP, File Send/Receive: TCP) （信息 发送/接收：UDP， 文件发送/接收：TCP） 1. Command 命令 1) Command functions (Low 8 bits from command number 32 bits) 命令功能（32位命令字的低8位） IPMSG_NOOPERATION No Operation
IPMSG_ANSENTRY 命令回发到上线新用户。 The new member gets the current member data by a IPMSG_ANSENTRY command. All members can communicate as long as an IP packet exists. 新用户通过 IPMSG_ANSENTRY 命令得到当前在线用户信息。所有用户在 IP 存在时可以互相通信。 An IPMSG_BR_ABSENCE command broadcasts absence mode cancel or nickname change to all members. However, an IPMSG_ANSENTRY command does not send a message back, which is different from an IPMSG_BR_ENTRY command.

mand process overview 数据包过程总览 1) Member recognition 用户识别 An IPMSG_BR_ENTRY command notifies a new entry to the current members at start-up. 飞鸽启动时 IPMSG_BR_ENTRY 命令向当前所有用户发送上线通知。 All members add the new member to their list after getting a notification message. 所有用户当受到通知信息时把用户加入列表。 An IPMSG_ANSENTRY command sends a message back to the new member.
