RS232 Control LED without MCU
« on: December 15, 2007, 01:38:44 AM »

Is it possible without MCU directly using RS232 to control some output device?

At this moment i just only need to control one LED and one Buzzer.
I just need to control 2 output signal. So, hope can design a very simple and no costly design and i just only have serial port TXD and RXD pin only.
I had seen other people did before, they had using MAX232 as a driver to control 2 output but i'm not sure whether their thing is work fine not.

Thank you.

Yes, that can be done.
