Title: Unibus map on 11/44's and the Versatec ?
Article-I.D.: n44a.126

	We have an 11/44 with a Versatec V-80 which we use for plotting and
printing. Our vp.c driver is the type which does raw i/o from the user
process rather than using up a kernal buffer. While this type of driver may
be better in many respects, lately, with more users, the system has hung up
waiting for the Unibus map to free up for a swap while the Versatec is
plotting.
	Any advice on how to get the best of both ?
