*IF* you have a system (or software package?) that can take advantage of it,
the 16550 is a better choice.  The 16550 has 16-byte FIFOs that can buffer
the data coming in.  If you have a real OS, like OS/2, you can set the port
for buffering and your system then only has to respond to an interrupt for
every 14 or so characters - instead of every character.  This really pays
off with high speed (9600 and up) modems.

Probably no advantage with DOS or Windoze, however.  I could be wrong - I'm
sure the net.vicious.psychos will let me know!  Direct all flames to
/dev/eatme.  Gosh, I'm in a nasty mood today. ;)

Oh yeah, JDR has the 16450 for $10.95 - 1-800-538-5000.  Active has a 16550
clone (by TI) - the TL16C55A for $9.95 - 1-800-932-7769.  Active may have
the 16450 cheaper too (I would think so if they have the 16550 for less
that the 16450 at JDR).  I don't have a catalog.  Even if you can't take
advantage of the 16550, I don't think it will hurt so it is a better deal
anyway.
