8051 Baud Rate Calculator

This utility program calculates baud rates for 8051-compatible serial ports operating in Mode 1 using:

You may specify non-standard clock divisors for Timer 1 and Timer 2.

Standard baud rates are used unless you enter a specific baud rate.

A list of standard oscillator frequencies and a description of typical uses for each is available from Vectron.
