Abstract: In one embodiment, a router establishes a serial-over-TCP/IP (Transmission Control Protocol/Internet Protocol) communication session between terminal units using raw-TCP encapsulation. For the session, the router maps serial characters to TCP out-of-band (OOB) communication fields, maps serial flow control signals to TCP/IP receiver-window advertisements, and dynamically adjusts a TCP/IP priority based on serial payload priority. Accordingly, the router may thus communicate data over the serial-over-TCP/IP session based on the mappings and priority.

Abstract translation: 在一个实施例中，路由器使用原始TCP封装在终端单元之间建立串行TCP / IP（传输控制协议/因特网协议）通信会话。 对于会话，路由器将串行字符映射到TCP带外（OOB）通信字段，将串行流控制信号映射到TCP / IP接收器窗口广告，并根据串行有效载荷优先级动态调整TCP / IP优先级。 因此，路由器因此可以基于映射和优先级通过TCP / IP串行会话传送数据。
