Apr 27, 2002 #2 B big&little Guest sorry ,would you like to introduce it in detial? mcu the type 8 16 32 bits? serial rs232 rs485 or others? when you have determined the two items ,you will have to choose the chips and relative software tools. good luck to you yours

Whole system ? Schematic ? Anyway, you have to find a RS232 interface chip (for example from TI). Then write software to handle the signal handsaking. This is not difficult. You can do it my yourself.
