Many of the early Unix implementations (and other OS) allowed you to
set the number of nulls you wanted to send after a CR.  The serial
driver code I have looked at in Linux appears to no longer do anything
if those options are set on the interface with stty.  Some assumptions
about things that can keep up being the only things people would connect
to these ports these days would be incorrect... obviously.

But, since I like connecting ASR33 and indeed other legacy terminal
devices such as TI Silent 700, DECWriter, etc to modern stuff, I just made
a little circuit with an ATMEL AVR that has a UART in each direction and
some buffer management/flow control code in the middle to speed convert,
add delays, basically put back the missing stuff that the modern OS or
terminal server has left out.
