AVR-Chat

In the files section of AVR-Chat, I have posted an assembly listing 
called 'SerialIO.asm' that does what you are asking for the Tiny11.


The code runs in the background as an interrupt process. It uses the 
timer fully so the timer can't be used for anything else.


  The routine is full-duplex serial and takes about 100 words of 
program code.  It uses four registers.




Good Luck with it.
