Have you compared the _full_ output from stty yet when Minicom and your
program are running ?

As I mention above, there are other possible failure modes and the full
output from stty will tell you if flow control is enabled on the port or
not. Checking the flow control is just the first thing I would check;
it is not the only thing.

Read the man page for stty. :-) You may save yourself quite a bit of time
if the flow control settings are not the problem.

Simon.
