TP-Link TL-WR703N 150M 無線迷你型 3G 路由器 OpenWrt TTL 通訊介面測試 (十一)

TP-Link TL-WR703N 150M 無線迷你型 3G 路由器 OpenWrt TTL 通訊介面測試 (十一)：

TP-Link TL-WR703N 150M 無線迷你型 3G 路由器 OpenWrt TTL 的串口通訊介面已經組裝完成，便可以測試 703N 的串口通訊，由於 OpenWrt 的會將 Uboot (Boot Loader) 的行程傳送到 Console (即 TTL 串口通訊)，祇要將串口通訊接到電腦，並啟動串口通訊軟件，便可以接收 Uboot 資料。

703N 路由器 OpenWrt TTL 通訊介面測試

電腦要啓用 Windows Terminal
ComPort：Com1

Baud Rate：115200

Data Bits：8

Parity：none

Hardware Shaking：none

電腦啓用 Windows Terminal 後，串口通訊介面接上電源，Windows Terminal 馬上接收到從 TL-WR703N 送出的 Uboot 資料，這樣 TTL 串口通訊介面是正常工作了。

Windows Terminal 接收 UBoot 資料
