Hey all. I'm trying to get my Dreamcast online but struggling to source a suitable modem. I found this on Newegg:
https://www.newegg.com/global/au-en/lenovo-43r1814-43r1815-dial-up-modem/p/1EC-00A9-00001
It appears to be using the correct Conexant chipset since, fortunately, they show the internals in the listing. It's not Dell or Lenovo branded, but the internals match the example given on this website's DreamPi troubleshooting page.
The only issue is that it doesn't mention if it's Linux-compatible.
If it matters, I'm in a PAL region (I've already built an 18v line inducer).
