	You forgot BSD 4.2/4.3 . It's about the same as UNIX V7, except that
I myself can Spawn stuff in one, namely:

	if (!fork()) execv(...) 

	Still, other people may want more control.  Also, the '0' entries
are misleading, considering that the number of things (options) you can do on
a UNIX TTY port is quite a bit larger than what you can do from AmigaDos or
MS-DOS.  E.g. MS-DOS takes 0 lines to do the above because it can't (easily)
do anything BUT the above... unless you've written library routines to do the
nasty stuff.

	(I'm not flaming because this article put VMS in a bad state... I hate
VMS)
