Yes.  There is a chip called the AM7910 (or 7911), produced by AMD. This
is almost a complete modem on a chip; just add power, line drivers and
go.  The chip supports FSK modes: V21 (300bps) V23 (600/1200bps hdx,
1200/75 fdx) and a Bell mode or two.  Not sure what the power through
this thing is like -- it's been around for a while.  Commonly referred to
as the "world chip", at least before V22/V22bis became popular.
