I don't know what VMS's solution is, but in Multics we solved it by
implementing a variant of the tty_write system call, called
tty_write_whole_string.  It guarantees that the string passed will be
sent to the terminal together.  The Multics equivalent of termcap uses
this system call whenever it sends control sequences.
