Yeah, I would say you don't need it. The gentoo guide was written with external USB plugin adapters in mind. These generally have an install image on them that loads first, thus the need to switch the mode. |

Most likely, the guide is talking about 3G adapters and was last updated in 2019 :) |

No, that tells wvdial to expect a standard AT device. Despite it being digital there is still a legacy device interface to setup the connection. |

Yes, like most things in classic UNIX/Linux there is more than one way to do something. |
| 126 |
|
| 127 |
wvdial will run a chat script and set up the modem, make the call, and then hand off. Minicom is a terminal emulator and you would be connecting directly to the device and issuing commands. If the the wvdial script failed, you run the commands in minicom to test, for example. |
