There are a number of function that where pointed out be the migration tool for porting over qnx4 code to qnx6.  Some I 
have been successful in writing replacement function for, but function that where supported in C's hearer file 'conio.h'
 have also gone away.  The migration tool suggest using read() for getch() and tcischars() for kbhit().  Can you give an
 example of how this is done?  There function seem to be designed for file pointer and not for stdin.
