Hmm.  I once needed this feature and added two capabilities to termcap:
sp= the escape sequence to send to the terminal (\E`\021 for HP's),
cp= what it returns, using the same % escapes as the 'cm' capability
(\E&a%r%3c%3Y^M for HP's).  In the absence of a standard way to do it,
this could as well be declared the standard -- unless there are conflicts
with other local additions of which I am not aware.  Since termcap is
slowly being replaced by terminfo, does anyone bother?  (Is that true
altogether?  What will be in 4.3BSD?)
