Set raw input (non-canonical) mode, with reads blocking until either a single character changes will not become effective without the tcsetattr() call. structure and then calling tcsetattr() to cause the changes to take effect.

(If so, is there any way to check if a write has completed?) That is the only thing I can think of since the writes are occurring fairly frequently and the first two are successfully sent. When I try to write other commands to it (there are bytes added to the write buffer every 15ms), I don't see any results even though the write() function returns 1 (write success). I am connecting fine and writing the first few bytes with success.

I am trying to write to a bluetooth device on MAC OSX using the unistd.h Linux functions in c.
