我在使用带有 openwrt 固件的 tp-link mr3020 路由器将 thuraya so-2510 卫星电话配置为调制解调器时遇到问题。
内部调制解调器驱动程序包运行良好，并且检测到调制解调器，我可以使用 AT 命令（minicom）与其交谈。
问题出在 ppp 配置上。

thuraya 公司有他们自己修改过的 openwrt，可以与某些手机型号配合使用
他们为 tp-link mr3040 开发了 openwrt 操作系统
我的路由器是mr3020硬件版本3
运行openwrt 23.5操作系统
任何建议或想法都可以帮助解决这个问题！！！
尝试过 noip 选项 尝试更改聊天脚本 尝试监视/提取 Windows-XP 和电话/调制解调器之间的命令 并在winXP连接中找到这些设置
