Responding to: ???'s previous message
Russ,

I am using the 8052 to control a stepper motor which should spin at a specific speed, this is TIMER interrupt driven task. The system has to listen the message via RS232. I just want to make sure while CPU control the motor it won't lose the message coming from serial port and vice versa. If the CPU can not handle them as fast as I expect, probably I want to use another processor ARM7 or something.
