Or probably rather that the Intel 8250 UART used the same clock equations, and it was used in IBM PC, and the IBM PC hardware implementation had no signal quality problems running at 115200 bps within reasonable cable length, so 115200 just became a de-facto standard that EIA could either adapt to or just become a bit irrelevant by pretending that it doesn't exist. -- (\_/) Copy the bunny to your mails to help (O.o) him achieve world domination.
