! 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
|
|
!
|
|
! Also read the comments in the signal.s file!
