+       ! 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!

+! Just as in the m68000 tail_mon library the acual signal system call

+! does the actual system call. On the m68020 machine the table was tested on
+! this `interface' did things that I did not understand, e.g. it called
+! a sytem call with number 38, called `_sysm68k'. I couldn't get the signal
+! system call get to work properly on that machine, but as it is clear
+! that this is in no way to blame to my back end table.
+! The system call as presented here does not reset the catch routine: a
+! signal that is caught by a user function will be caught every time, not
+! just once. I couldn't change this.
