请教吉比特H2-3s的 TTL接找密码: x3 J" h5 F, [7 m9 @+ X0 e, s1 ]
' H8 w6 a% ^' D2 g+ b$ t+ a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、、、、、、

! E8 x' Y% n& ~( M) g \* p0 @8 O9 I2 ^4 S* ^; B: B
这个是我怀疑是TTL，但是连接没有反应，" e @7 G9 A/ G7 R
----------------------
% q* f$ Q d- A) {/ r/ N6 B3 h( _ 7 U# o# ~7 o+ L
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？？？

. Q+ ]3 F, H V# f/ H7 \- r8 \rx tx gnd vcc* y+ j0 d! }2 t$ l1 p) E5 T G
我的连接是，rx接的下排的，tx接的上排那个，gnd 接的下排。这样对吗？？？===========================================! o! n* E$ q7 }4 n7 F( Z
*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 。
; h/ H$ u9 v' j [/ v, Dttl连接后信息显示正常，回车后中断启动。停留在# 光标处。0 G4 y; t* G' P R1 @+ y
但是输入shell，以及其他的提示错误，查看命令有以下：% c6 I2 n* l6 N, u: g

) J3 m$ s+ M0 x. j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？？？6 r/ ?1 {; s4 H- A
不知道怎么整了，请求大神。* S% K$ E7 `7 x$ G* [" k. _! m& v. z" n
