你没看错，就是以前那种打电话上网时的拨号音！前段时间为了用电子传真，专门淘了个USB口的Modem，免驱的，没想到还能拨号上网！昆明电信，16300,16388都能打通！

注意：
1.同时接入宽带和窄带后，系统优先使用窄带网络
2.现在拨号上网或ISDN的话，聊天可以，网页基本上只能开一些简单的，本论坛还行，百度贴吧之类的别想
You're not mistaken, it's the dial tone from the old days when making a call to go online! Some time ago, I specifically bought a USB port modem for using electronic fax. It's driver-free, and surprisingly, it can also dial up to go online! Kunming Telecom, 16300 and 16388 can all be connected!
Recording environment is as follows

Note:
1. When both broadband and narrowband are connected simultaneously, the system preferentially uses the narrowband network
2. Now for dial-up internet or ISDN, chatting is okay, but for web pages, basically only some simple ones can be opened. This forum is okay, but don't even think about Baidu Tieba and such
