我正在使用 GPRS 调制解调器并想在 eCos 上通过 PPP 建立连接。但是无法拨号成功。这个调制解调器在 windows xp 上运行良好。“LCP：发送配置请求超时”的原因可能是什么？请提出建议。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", "ATE1",
"OK", "AT+CGDCONT=1,\"IP\",\"internet\"",
"OK", "ATDT*99#",
"CONNECT", "\\d\\c",
NULL
日志如下。
