Eric - I am certain that this function will exist electronically in some
TU's from the 70's/80's.

The more traditional way of handling this is to configure the stunt box so
that CR by itself does CR+LF. This was generally called "Non-Overline"
configuration. Some details are here:

If you google for "Model 28 stunt box" you will find some wonderful
Teletype brochures on the ability of the stunt box.

You will not find a lot of discussion of mechanical TTY's on CQ-Contest and
RTTY contesting mailing lists. But I believe there is a "Greenkeys" mailing
list that specializes in the mechanical units.
