You need to set raw mode for the TTY device I think. Maybe Ed can give you the
function name you need to call to do that?
Yes. You need cfmakeraw() to do that (or do everything yourself). See
src/lib/libc/gen/termios.c to see what it does.
So what I'm interested in, is the following:
"even that device is answering requests slower and slower until
it stalls completely within 1 hour"
Could you run `pstat -t' to see what's going on when it stalls? This
nifty tool just gives some random statistics on TTYs. Very useful to see
what's going on. Where data is stuck, etc. etc.
Here is what I get from pstat when I run my executable:
while ( 1 )
while? pstat -t ttyU0 | grep ttyU0
while? sleep 1
while? end
