Disable RX on UARTS

2005-06-15 by extra300_it

Hello,

I have an external circuit that echoes back the caracters that I am 
sending out of UARTs.
Is there any way to disable RX while I'm transmitting (like Rx Enable 
on other micros)?

-I am using FIFO-

I disabled both RX interrupts during transmission.
When tx is ended, I clear FIFO buffers (UxFCR bit 1)
This should clear the RX FIFO buffer, isn't it?

When I re-enable RX interrupts I get in RX several times the last 
char that was sent.

Any suggestion?

Thanks.
