If the terminal has no pad character, there is no way to introduce a delay
instream within the terminfo sequence. I'm afraid that you don't have much
recourse with the pad sequences $<n>, but will have to use something like the
iprog to do the initialization. Even mandatory padding ($<n/>) doesn't help
without a pad character.

The question is how? You need to do the output delay at the time that the
sequence is output, which may be far removed within the program from when the
output gets sent to the terminal.
