[avr-gcc-list] Problems with ATMEGA8 USART

[juan antonio jimenez martinez]

Hi, Im experimenting some details setting the ATMEGA8 usart, for example, I 
have an interrupt driven routine for receiving data, may problem is how can 
I clean the buffer in orther to let it ready for the next reception, I mean, 
when I send  two chars from my computer to the ATMEGA, the interrupt routine 
do what I want , but when I send 10 chars, the buffer that I use to read the 
incomming data, reads the two chars that I have send before plus the new 
data and as a result I got  the 10 chars message incomplete due the two 
chars that I have sent before

I hope some one know an answer, because I have tryed with the RXC flag and 
it seems not work,  or how can I select the sise in bytes to read at one 
time, and again flush all the RX usart buffers


thanks

Jimenez
