You don't, 14400 isn't a rate available to uarts.  It's a common error
among some folks who have 14400, 28800, or 33.6k modems, who incorrectly
assume that the modem must be talked to at the 14400, 28800, or 33.6k
rate.  It isn't so.  First thing, all those modems have autobaud
detection, and will set up automatically at any rate you speak to it at. 
Second, they have features like compression and error control, which
require that they communicate _faster_ than the line rate.  Most folks
talk to their modems at 57600 or 115Kbps.
