Why is the MM deals with Ethernet adapters in the first place?

"Using an old V.92 Haynes modem"

  I think perhaps ModemManager may be misnamed. It can't handle old style
  external modems such as my V.92 Haynes modem plugged into serial ports.
  But there are situations (for example ADSL goes down) where I would need
  to bring up an Internet connection using my V.92 Haynes modem over
  dial-up ppp. Is that even possible with NetworkManager? 

  ...
  In the next few days I'll be getting a serial to USB cable to plug my
  old V.92 Haynes modem into and see how I get on with that. 
  
  I also have a P166 with serial port with which I can test. Might be nice
  to have a back-up dial-up Internet for those occasions when broadband
  goes down.

  Hi!
  
  Here's the first step in adding 56k modems capability to NetworkManager
  through ModemManager. There's still work to do but it is a good start ;)
  
  Let me know if this is all good :)

  Regards,
  Alex

Perhaps in meantime TSP switched POTS/ISDN to VoIP/IMS?
