   No, you need an actual serial port, at least as far as I am   
   aware.   
      
   USB to RS232 are all non-standard (I've been told).

   Yeah, if you write a driver for every device, that would   
   work. And that's basically Windows. You buy an adaptor,   
   and it comes with a driver, and it works.   
      
   But for Seabios to do something useful, without a driver   
   for every device, then some things are ruled out, including   
   the non-standard wifi (so I've been told).   
      
   But there are things that are reasonably standard, so you   
   can write a single driver for them. TCP/IP stack. USB stack.   
   And the NDIS protocol for USB tethering.   
      
   Then you could use the Hayes AT standard (or close) as   
   a virtual modem, and other standards like nntp, and you   
   can start doing various useful things.
