;;; Constant definitions for tty control code (POSIX termios).
;;; Copyright (c) 1995 by Brian Carlstrom.
;;; Largely rehacked by Olin.

;;; These constants are for NeXTSTEP 3.x, 
;;; and are taken from /usr/include/bsd/sys/termios.h and
;;; /usr/include/bsd/sys/ttydev.h

;;; 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
;;;	  ttyl/xlcase				xlcase		Vas ist das?
;;;	  ttyl/xeucbksp				xeucbksp	'n das?
;;; - Some baud rates
