使用linux建立PPPD连接以与调制解调器通信

当PPP试图与模块建立通信时，我在日志文件中收到以下消息：

Serial connection established.
using channel 6
Using interface ppp0
Connect: ppp0 <--> /dev/ttyO5

Receive serial link is not 8-bit clean:

我的聊天文件是：

ABORT "BUSY"
ABORT "NO CARRIER"
ABORT "Username/Password Incorrect"
SAY "Starting chat file \n"
'' AT
SAY "\n ATE0"
OK ATE0
SAY "\n AT#SELINT=2"
OK AT#SELINT=2
SAY "\n AT+IPR=57600"
OK AT+IPR=57600
SAY "\n AT&K3"
OK AT&K3

OK AT+CMEE=2
SAY "\n AT+CPIN=6512"
OK AT+CPIN=6512

OK AT+CGDCONT=1,"IP","internet.vodafone.pt","0.0.0.0",0,0
OK AT#USERID="vodafone"

所说的字符串仅用于日志跟踪。

您好，您是否尝试过通过AT命令和类似wvdial或Hypperterminal的东西手动连接，这是否有效？是的，它有效，实际上我在聊天文件中发现了一个错误，现在它部分有效。现在，当PPP尝试设置与模块的连接时，我在日志文件中得到以下输出：串行连接已建立。使用通道6使用接口ppp0连接：ppp0/dev/ttyO5已发送[LCP ConfReq id=0x1]已发送[LCP ConfReq id=0x1]已发送[LCP ConfReq id=0x1]LCP:超时发送配置请求连接已终止。接收串行链接不是8位干净的：问题：所有的位7都设置为0注释有点难以阅读，因此如果您仍在寻求帮助，请使用此信息更新问题。
