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 ? Dan Ts'o ...decvax!cca!ima!n44a!dan
