New things in this distribution:

Multiple Console Servers

The client can now connect to several machines in succession when
searching for a particluar console. The config file has changed
to reflect this, replacing HOST with HOSTS, which is an array of
strings, with a NULL string at the end. Note that only the client
software needed to be changed to accomplish this.

This introduces one bug, but I'm not likely to fix it: the mechanism
for finding unique abbreviations can't work accross multiple console
servers. For instance if you say "console tr" wanting to get "tree"
on the second console server, you may get "tribe" on the first
server, since it can't know what the second server has. The reason I
won't fix it is that the cleanest solution is to stop accepting
abbreviations, and I happen to like them.


Carrier Detect

The TIOCSSOFTCAR ioctl is used to turn off (ignore) carrier detect.
The tty must be opened O_NDELAY for this to work. If you want to
use carrier detect, set the variable "softcar" to zero.


Serial Line Break

I switched from using TIOCSBRK and TIOCCBRK, to TCSBRK, for
generating the line break. We had a problem under SunOS 4.1.1, with
a scsi terminal interface, where the old way didn't work (I can't
imagine why the original method would fail - they _should_ be
completely interchangeable).


Paper Included

A plain text copy of the LISA conference paper is included. I would
have included a troff formatted copy, but their troff macros seem to
be a bit non-standard.


Alternative Sources

There is now, or should soon be, another version of the console
server available at j.cc.purdue.edu. For information, send mail to
ksb@mentor.cc.purdue.edu (Kevin Braunsdorf). I'm not sure at this
point of what all their changes are, but here's some of them:

They use cbreak mode instead of raw, which give them more
control over the connection, including things like backgrounding
connections, but makes the connection less direct.

They added various features to the command set.

Changed the command line parsing (more standard, probably)

They worked on a problem with silo overflows (we haven't had
much of a problem with that here).
