For example, is something like
wget available in Windows XP?
if its dos proper (windows command line is NOT called dos - its the cmd shell), you can use Arachnae, else emgee's suggestion of lynx sounds like a good bet.
If you want a built in solution, use
telnet www.superuser.com 80
and type in raw HTTP commands.
If you need a browser, then maybe you can use cygwin and a text mode browser like lynx (there's a site dedicated to a windows port).
If you need a real DOS Browser (16-Bit), there may be some as well, haven't looked.
Do you mean you want a win32 compatible text-based browser?
You can try a win32 version of Lynx -> http://pachome1.pacific.net.sg/~kennethkwok/lynx/index.html
