UUCP and Flow Control
We have this problem as we run an Ungermann/Bass
broadband system around campus which is not transparent.
(we do a lot of TCP/IP so uucp is not critical to us)
I thought about this problem and the fix I proposed
(but never implemented) was to teach uucp to talk to
a psuedo terminal with the back-end process on the other
side doing whatever escaping is needed for the stream.
A socket could accomplish the same thing (or of course
yet another ioctl().) Obviously the UUCP at the other
end would have to do the same thing but I believe this
software could be incorporated exactly the same as
one incorporates a new modem into uucico (actually simpler
as once it opens the psuedo device the other process
could pick up a lot of the work.) Any thoughts?
TCP/IP UNIX support
It seems to me from the literature that DEC's ULTRIX
accomplishes this well for a VAX buyer. Certainly
there are a number of workstations (SUN) that should
have this property [I have no idea about SUN's software
support.]
Yet another statement about O/S's:
I personally think that the whole point is rapidly
becoming moot. With the ability to put >VAX780 power
deskside we are heading for a world of workstations
and (a few) central servers. I am not sure I would
want to run either UNIX or VMS on my workstations.
Both are designed to be timesharing systems with a
presumption of techical expertise and intervention.
When each of your users has his/her own system can
you seem them (UNIX) maintaining /etc/ttys, sendmail,
host tables, gateways, fsck, uucp (VMS) logical names,
device queues, decnet/NCP???? Not I. Besides, who needs
all the damn overhead/complexity of accounting, file protxn,
and process scheduling (ok, some you need) on my desk?
I think all these time-sharing systems will have to evolve
(rapidly, like for us maybe w/in a year) to server systems.
For the last year I have been using the XEROX1108 (Dandelion)
LISP machine. I think it is much closer to what lies around
the corner (yes, you can make good use of it w/o knowing LISP.)
