Well, I finally tested it over here, and what I found is: If the line has a \r among the first 16 bytes, then the information is TXed immediately. If there is no \r in the first 16 bytes, then the information seems to be buffered.
Where in the driver is this happening?
So, it seems that that the patch should ask the driver to TX the information when we receive a \r or when the buffer is full. Does it make sense to you ?
Not sure. I just wonder why the data is disappearing rather than getting buffered somewhere. Clearly the other serial drivers are doing that successfully. I don't even know why the driver should care about the contents at all. Just send data when it is ready. -- Len Sorensen
