(1) If you design a system to communicate with a 115200 N81 RS232 system by dividing down a 400KHz master clock, how many bits can you transmit in a word before a transmission error occurs due to clock skew? In other words how many bits long can an RS232 word be in this system before the clock exceeds 50% of a bit time?

(2) If the designer has the ability to modify the clock slightly what frequency close to 400KHz could be used to interface with a 115200 N81 system and gaurantee that words of length 12 can be transmitterd with less that 30% skew in the 12th bit.
