Replying to a message of Tim Hutzler to Benjamin L Mcgee:
 TH> What you are describing is a FIFO, or queue. They both work

You mean "LIFO stack" (a redundant term, because a "stack" is a LIFO buffer). 
A buffer is simply a place to hold data before it is needed. Yes, what he 
wants is a queue.. ie. a FIFO buffer.
 TH> Also, when you stated. "Any data that could not fit in the

 TH> (overflow) data will be lost? I don't think you want that,
 TH> but I need to ask.
That is how a UART operates :)
