+ * There are several kinds of tty drivers to contend with.  These include:
+ * (1)	V6:		no CBREAK, no ioctl.  (Include PWB V1 here).
+ * (2)	V7 research:	has CBREAK, has ioctl, and has the tchars (TIOCSETC)
+ *			business to change start, stop, etc. chars.
+ * (3)	USG V2:		Basically like V6 but RAW mode is like V7 RAW.
+ *			(We treat it as V6.)
+ * (4)	USG V3:		equivalent to V7 but totally incompatible.
+ * (5)  Berkeley:	has ltchars in addition to all of V7.
+ *
+ * The following attempts to decide what we are on, and declare
+ * some variables in the appropriate format.  The wierd looking one (ttymode)
+ * is the thing we pass to sTTY and family to turn "RAW" mode on or off
+ * when we go into or out of visual mode.  In V7/V6 it's just the flags word
+ * to stty.  In USG V3 it's the whole tty structure.
