You should probably allow errors below 2% or something like that.  The
async 8N1 protocol allows for more error (but that depends on how the
receiver samples the data) and it isn't uncommon that the error is 1-2%
at higher baudrates (besides, there are devices with more limited baud
generators, which may have "large" errors at lower rates as well).

Some software (minicom, for example) doesn't let you to type in the
baudrate, so if the only way to get 115200 bps out of your driver is
to ask for 113636 bps, you won't be able to use minicom at all :-)
