 		 #163952 - Let's see ... What is wanted here ...
Responding to: ???'s previous message
I seem to recall that you want to transmit at one rate with one protocol, and receive at another with a second protocol. Is that right?

Couldn't you simply do that with one UART for transmit and the other for receive? Doesn't that allow you much more freedom in your crystal selection?

Is possible? AT89S52 with dual serial baud rate            01/01/70 00:00      
   yes...            01/01/70 00:00      
   Use Timer 2...            01/01/70 00:00      
      Can I have both at same time?            01/01/70 00:00      
         you can't have different baudrates...            01/01/70 00:00      
         YES            01/01/70 00:00      
         No, unless...            01/01/70 00:00
