SCP/Microsoft 20HAL uploader

[Richard Cini]

Excellent! That’s a great piece of info. Not sure why a TOPS-10 command would be embedded in a program like this. The notion of filtering/delay itself makes sense but that command would make sense only if IBM had a DECSYSYEM too, no?

The TOPS-10 manual says that:

    (SET) TTY FILL n

sets delay characteristics for the line to class `n`.  There's a table
of the number of filler characters sent after each of a number of
different control characters.  Class 3 uses the most fillters.  The
filler characters used are CR after a CR, and DEL after all the others.

It could make sense to do this during a file transfer, depending on the
assorted endpoints, etc.
