UART is on the card that you modem cable plugs into at the computer 
level...not the modem.  The 16550A UART offers a 16K buffer for high speed 
modems.....it help prevent data errors.  I've used external modems for 
years...I'l saw a lot and have NEVER saw one where the 16550s were on the 
modem. On the other hand, the internal modems do....and should.
All the best.
Sincerely,
