Dears friends

i am a Newbie with avr programming. At this moment I have a problem
very serius. I am using a at90s8515 and trying to put a software
uart to operate in my system, i need two of then. Afert a long time
trying my own code without sucess I decide to use a code from atmel
in assembler. My code and atmel's code show exact the same estrange
problem. I can send any caracter combination, but $0D, in other
words, my code send and receive any catacter, but when i send #0D I
receive a #0D #0A, With atmel's code I have exact the same problem.
Can some body help me? I must talk I tryied all possible time delays
and conbinations, either no code is sent or I receive a #0D #0A
always what sent just one #0D. Please help me. Any tougths will be
wellcome

Thanks in advance

Sounds like your terminal has been set to send a line feed when you
send a return :)
