Null needed after cr/nl.

[Dave Martindale]

v7 and later tty drivers derived from it (32V, 4.XBSD, etc) have several
bits in the stty "mode" word which control the presence and length of
various delays. 
In particular, you will probably find that one or more of the bits making
up CRDELAY or NLDELAY is set (the manifests are in /usr/include/sgtty.h
or somewhere similar).  Stty should let you turn the delays off.
The default delays you get, which may be different at different speeds,
are set by /etc/getty.  They may be compiled into tables inside getty or
read from a file, depending on what version of UNIX you are dealing with.

The most conservative assumption a system maintainer can make is that
some terminals which dial up his machine may need delays, and so have
them on by default.
