Linksys WRT54G路由器板子串口焊接出串口和JTAG口。
板子串口为TTL电平，接到PC串口需要经过转换。
但我为了省事，我用Simens 2118的串口数据线C35 cable改造。
可惜这组装线省掉了转换芯片，当我把Tx,Rx,GND都接上后，输出只有1.75v 
没办法，改用Simens M65的USB cable 510，猜想应该会好点。
按照接口定义接好后发现输出部分乱码，没办法，国内组装线得怀疑一切，
拆开接口后发现11脚GND居然是悬空的
没办法，把地联上黑色的GND线，可是最后的结果居然还是一样的！
有兄弟知道这个现象是啥原因吗？线过长？大概1米。
难不成还是要我找MAX232焊？
