It should be possible to run it under SysV.
I've ported it to run under a SysV Rel.3 with 'only' Internet Sockets.
It think it should work with named pipes or straems also.
If don't want disconnecting normal pipes should do.
The only essential thing is to have pty's or a clone device like ptc
and to have a select system call or a pool system call to wait for
multiple handles too become ready.
I've also added a permanent status line for Terminals that have one.
I don't know if MINIX got this features because I have'nt had time to
look at it close enough.
