I'm not sure why but I created a char *, write the char to it and it works that
way instead of including the hex in the write function; something like
write(fd, mychar, 1) instead of write(fd, "0x16",1).
difference?
Is this the only way for user program to write bytes to an IO?
Thanks,

can anyone offer any advice here?Show us the code!Really, that's the way OSS
works.There may be a stupid mistake, but it's impossibleto guess. Seeing the
(eventually reduced) source codeis basically the only way to get helpful
advices. Gabriel.
