;;; Copyright (c) 1995 by Brian Carlstrom.
;;; Largely rehacked by Olin.

;;; Non-standard (POSIX, SVR4, 4.3+BSD) things:
;;; - Useless ttychar/quote char.
;;; - Two extra newline delay values
;;; - Some control and local flags:
;;; ttyc/2-stop-bits-when-110-baud stopb110
;;; ttyc/parity0 par0
;;; ttyc/parity1 par1
;;; ttyl/crt-delete echocrt
