我按照提示的文字链接后能读取TTL信息,但是无法中断TTL,无法输入控制命令。是连接不对还是怎么的,请教大家、、、、、、

按照这个连接,两排接口,我就是能读取信息,但无法中断和回车输入指令。 是连接不对还是怎么的???" V* R: z, x2 S" X4 \1 m, s: c) v- D

6 g3 e% f- z4 L* {/ D*经大家指导,正确连接应是连接上排的几个,从左到右分别是 rx tx gnd vcc 。2 m# c: R) e A8 C o: F7 v; l$ `/ m
ttl连接后信息显示正常,回车后中断启动。停留在# 光标处。

在后续启动中回车能出现login 和passwd 等,但是输入时系统也自动有信息加入,感觉无法正常输入登录。难道是我输入用户名和密码不对???
