[BeTZ]

hi,

I've a project using RTX-51 operating system. And I need to use UART, my problem is i can't use UART isr in RTX-51 OS. It seems that something wrong with my code...,
and I'm using Proteus Simulator for help me.

You need to set...

REN = 1; //for enable serial receive
ES = 1; // for enable serial port interrupt and
EA = 1; //for global interrupt enable



May be you forgot it, try to put it on your UARTInit ()
