hi can anyone send me schematic diagram for microcontroller 8051 and UART 16550 thanks omnath@rediffmail.com
See this thread: http://www.keil.com/forum/docs/thread2298.asp. Or why not try a Triscend E5 - then you can build as many UARTs in the on-chip logic as you like! http://www.triscend.com/products/e5.htm
