What are some modern uses for a 56k modem?

[RenaKry]

I—for all intents and purposes, a zoomer who’s earliest memory online was dialup internet—have recently built a Thunderbird-based computer that has a PCtel HSP56 audio modem riser (obsolete expansion slot for modems in the late 90’s) installed. Although the motherboard has 10/100 Ethernet for effortless internet connectivity (drivers and outdated browsers notwithstanding), I left the modem in, because I have nowhere else to put it.

 

I am now wondering what a modem can be used for in 2021. I pretty much know next to nothing about these devices other than the fact they transmit data over a phone line and that they were commonly used to dial into Bulletin Board Systems. Since telnet has basically succeeded modems in regards to BBSes, what are some other questionably practical uses for a 56k modem in a computer running Windows 98 and DOS?

Besides that i have not seen one in use for a long time. Even fax machines are starting to die out finally.

Only place i find those are with old doctors

Telnet isn't a replacement for a modem, you'd still use Telnet or similar, even after you connected to a BBS. The modem itself doesn't provide any UI for you to interact with something like a BBS, you know; you still need an app to do that.
