! Two system calls (gtty and stty) in the m68000 tail_mon library ! were not really system calls but they used _ioctl. The m68020 machine ! the table was tested on used real system calls, and we'll use ! them here. ! There were also three calls (ftime, lock and dup2) that were in the ! m68000 library, but were not included in the list of system calls ! for the m68020 that was given to me. We'll include them anyway. ! The original gtty and stty files are included here. ! Note however that the 68000 machine (the Mantra) needs the parameters ! to system calls in registers, while the m68020 machine this table was ! tested on wanted the parameters on the stack ! !
