Implementing UART communication

Dear all. I need to implement UART communication for high baudrate (by interrupts). My communication must be implemented as described below: RECEIVING: rcv_buffer up to 255 bytes. ...

This can be achieved with baud rates as low as 38400.

This is typical ;-)

It's not clear to me what you mean by this ... but you should have little difficulty

handling the scenario you describe ... even with a very modest cpu clock.

What is your question?
