Hi Members,

One of my applications require an additional UART Port for MCS51 (P89C61X2).
1. PCB is already designed to use a software UART, so I do not want to change the PCB layout.
2. Required BaudRate is 2400 or 1200 only, Max. 4800(once in a blue moon).
3. It is only recieving data from the master unit...No transmission.
4. Timer 1 and Timer 2 are free (not used). Timer 0 is used.
5. Urgency: "Product was to be delivered, Yesterday" - basis.
6. C source Code, prefered. I tried the "Search", on this forum, and followed the links, but most of them are not working, hence I am starting this thread.


Thanks,

but did not work.
I got this link from this page;

It is mentioned that this example uses UART in interrupt driven mode.
