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. > Also usb_modeswitch is in portage.

Despite it being digital there is still a legacy device interface to setup the connection. > Does using wvdial result in no need to use minicom like mentioned in [2]? > Yes, like most things in classic UNIX/Linux there is more than one way to do something. 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.
