Unless you're turning off interrupt handling (masking them) for long periods or you have Interrupt Service Routines taking longer than a few microseconds, there's no chance of not keeping up with 115200 baud even when using interrupts on unbuffered UARTs. However, buffered UARTs are MUCH more efficient because you can make them low priority interrupts and run faster than 115200. For the safest approach unless you absolutely need the serial speed, run somewhere slower like 38400 or 19200.

Hi,
Thanks!
Actually i'm not doing anything for now but receiving bytes imfrom the uart.
I'm working with 19200 baud rate.
The thing is that the interrupt mode not seems to work. I'm still receivig only the last byte from each string.
I unchecked the small c library and the reduced driver and still not able to recieve all the characters.
Any idea why is that happening?
