Were 19.2k modems very popular?  It wasn't a ITU standard: V.32terbo. 
It's known as a proprietary protocol.  I think it wasn't long after the
19.2k's that 28.8k, V.34 was introduced  (an ITU standard), and
became very popular.  V.32terbo sounds like an ITU standard but it's
claimed the ITU didn't approve of it.
