我正在使用GPRS调制解调器，并希望在eCos上通过PPP建立连接。但它无法成功拨号。这个调制解调器在Windows XP上工作正常。导致“LCP：超时发送配置请求”的原因是什么？ 请给出建议。 非常感谢！
我的聊天脚本如下
"ABORT", "NO CARRIER",
"ABORT", "ERROR",
"ABORT", "NO DIALTONE",
"ABORT", "BUSY",
"ABORT", "NO ANSWER",
"", "AT",
"OK", "ATS0=0",
"OK", "ATE0V1",

"OK", "AT+CGDCONT=1,\"IP\",\"internet\"",
"OK", "ATDT*99#",
"CONNECT", "\\d\\c",
NULL
日志如下。
