	I'm trying to find out if anybody knows how to add a new line
discipline to the IBM RT-PC 6150. We are running AIX 2.2.1 and as far as I
can see, there is no obvious way of doing this.

	One more problem I am having is with the porting of a multiplexing
windowing terminal device driver. In the driver open routine, I am calling
the line discipline open routine but this always hangs the machine on the
second open. From my past expiriences, all the line discipline open routine
does is attaches a cblock to the read buffer and sets/resets a few flags.
So what I did was rather than calling the line discipline open routine, I
did the work myself which cured the problem. What I can gather from this is,
I am not filling in the tty structure correctly especially as there are a lot
of new additions to this stucture.

Any ideas would be greatly appreciated.
