[net.unix-wizards] Pseudo TTY Drivers -- Need Help!!!!

pavan@omsvax.UUCP (Pavan Nigam) (05/02/84)

      Can any of you wizards help me out with getting pseudo-ttys
      on System III.  I am porting my program (a window manager)
      from berkeley 4.2 to System III, and I am looking for a
      pty driver since System III doesn't have any.  Can you give
      me pointers on porting the 4.2 driver to system III.

                                            Thanks.

                                         Pavan Nigam

Note that 4bsd uses a IN|OUT flag in Ioctl's, so code in tty driver
may have trouble if it uses copyin() and copyout() instead of bcopy().
