Hello! Just a quick question: I am planning on using RS-232 ACIAs to send serial data to a 65c02 computer. Any (older) RS-232 chip supports no more than 2 MHz clock speeds per serial pulse and the newest chips only support up to 14MHz. In this instance, should I use a PWM pin to simulate the 1MHz clock required by the RS-232 chip? And what is the best way to ensure the Arduino waits until the PWM pin is done with its clock signal before moving on to the next step/bit?
