I've been tinkering around with line disciplines, and have been having problems with the bottom half of the input side. It appears that l_rint will stop passing characters up at 19200 at around 1K (or so t_rawq.cc states). Is there any way to safely increase this to around 8K, or even 16K? The reason I ask is that the board I'm working with has an 8K receive buffer, and I'd like (for the sake of efficiency), be able to move nearly a full buffer of data at once, but I seem to be limited by this number. I've taken a look at tp->t_hiwat in the termios structure, as well as c_cbmax in the clist structure, and neither seems to collate directly with this limit in to the clists. Can anyone comment, and possibly get me past this? Thanks. -Brian
