+ * There are several kinds of tty drivers to contend with.  These include:

+ * (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.
