hide cursor command doesn't respond on '634 disp

Clarifying earlier msg; can't get '634 commands to have an effect.
Do I need time delay?

For example, to hide cursor, datasheet says ctrl-D
putchar(4);
should do it ?

I would think that would work.

Please use CFTest to make sure everything is connected correctly:

and if the \004 (in CFTest speak) works there, then there must be something in putchar() or the port settings that is amiss.

Some of the library functions can do character translation under the sheets.
