	Of course it can be used for dial in connections, that's what
happens at the ISP end of the connection. It can also be used for fixed
point to point connections over directly wired connections or leased line

	All of this is covered in great detail in section IV of the
handbook - 27 Serial Communications and 28 PPP and SLIP.
