Or, what about implementing the "better" scheme yourself, and provide, not a single monolithic replacement terminal handler, but a number of sub-handlers each of which controls each orthogonal feature etc.... Might this, however, lead to potential performance problems? -- |------------Dan Levy------------| THE OPINIONS EXPRESSED HEREIN ARE MINE ONLY | Bell Labs Area 61 (R.I.P., TTY)| AND ARE NOT TO BE IMPUTED TO AT&T. | Skokie, Illinois | |-----Path: att!ttbcad!levy-----|
