Cello WWW Browser
Beta release .8
5 November 1993
--------------------------------------------------------------
What is Cello?
--------------------------------------------------------------
Most of you already know this, or you wouldn't have grabbed the
file -- but we get mail from people who have downloaded the
package without knowing what it is. This part's for them.
Cello is a multipurpose Internet browser which permits you to
access information from many sources in many formats.
Technically, it's a WorldWideWeb client application. This
means that you can use Cello to access data from WorldWideWeb,
Gopher, FTP, and CSO/ph/qi servers, as well as X.500 directory
servers, WAIS servers, HYTELNET, TechInfo, and others through external
gateways. You can also use Cello and the WWW-HTML hypertext
markup standard to build local hypertext systems on LANS, on
single machines, and so on. Cello also permits the
postprocessing of any file for which you've set up an
association in the Windows File Manager -- for example, if you
download an uncompressed Microsoft Word file from an FTP site,
and the appropriate association exists in File Manager, Cello
will run MS-Word on it for you. This same capability is used
to view graphics and listen to sound files you get from the Net.
To run Cello, you need the files in this archive, plus some
flavor of Winsock TCP/IP stack -- a piece of "middleware" which
communicates with the Net. Cello works with all of the
following (to some degree or other -- Winsock is pretty new,
and there are some buggy stacks out there. Not that Cello is
exactly pristine either...):
Trumpet Winsock by Peter Tattam (freely available from ftp.utas.edu.au)
Distinct
FTP Software (please upgrade to the 1.09 version of their DLL)
Lanera
Beame and Whiteside
Frontier
LAN Workplace for DOS
Notes on the installation of Winsock are usually available with
the distribution.

Notes on the Alpha WINSOCK version.
--------------------------------------------------------------
Please note that most of the installation information in the
CLOHELP.HLP file (the online help system) is outdated and will
be replaced in the next version -- it pertains to the older,
Distinct TCP/IP version of the software. There are also many
features which are not documented online. Again, this will be
fixed in the next release.
Documented problems which aren't fixed yet:
-- Cello's builtin Telnet client has trouble with some SunOS
and ULTRIX machines (and maybe more). For some reason these
expect an <LF> character as the carriage-return prior to
login. A typical symptom is that the host machine will give
you a login prompt, you'll type the login name and hit <ENTER>,
the cursor will return to the beginning of the line, and
nothing else happens. To work around this, use <CTRL-ENTER>
instead of <ENTER> to send the host machine a <LF> character.
Another possibility is to use the Use Your Own Telnet...
feature to splice in a telnet of your own.
Undocumented features:
-- You can start Cello with a URL on the command line; Cello
will "jump" to that URL on startup.
-- The Configure/Use your own.../Telnet client feature expects
you to enter a command line for your telnet which looks
something like:
c:\somedir\mytelnet #h #p
where #h and #p are placeholders for the hostname and port
number. If by chance your telnet doesn't support port numbers
at the commandline (many don't), just use the #h placeholder to
tell Cello where the hostname should go in the command line.
If you do this, Cello will use your Telnet to connect to any
Telnet host which is using default port 23, and will use its
own telnet when it needs to get to an unusual port number (a
relatively small percentage of the time).

Have fun with it.
