X windows on Microport 286 Unix

[trevor]

	I am attemping to port x windows to Microport 286. Is there anyone else
out there attempting to do the same. I have a couple of problems.

1)	imake calls ftruncate and vfork. Could anyone tell me what these
	functions do?

2)	Has anyone had thoughts on how to implement the serial bit stream as
	microport 286 does not support sockets. I suspect the best way is to
	write pretend socket drivers. Does any one know if this is avaiable
	in the public domain for system V.
