I am using AT89C51.
I need two uart in my application. One uart is available in MCU.
Second I am thinking to implement by digital I/o's
Is there any reference code available for this.
I am using Rx,Tx & Gnd only.
Data can rx/tx simultaneously on both uart, so rx procedure has to be in ISR.
Tx should be ideally high so can I put a 10K pull up on tx line
