I'm having some telnet problems, and wondered if anyone could tell me why.
A lot of times when i telnet out, my link is VERY bad.  Recently, it's
been freezing up and i have to disconnect.  When i get back to the site i ws
at, it thinks I never left untilI disconnected.  The other problem I've 
been having is if there's a lot of spam, it just knocks me right off the 
site.

any ideas?

No ideas off the top of my head, but does the problem occur only when
you telnet to one particular site, or does it occur with several sites?

I don't telnet to very many sites.  I'l have to check some others and see what
happens...

I +just+ had a problem with telnet and control of the session.
  
I have my help flag flying (almost) always on Grex. I telnetted
to another machine, logged in and was dong stuff normally.
  
Then I got a help request from a Grex login .......... Oh, boy,
was I lost .... How to answer or chat here without closing
teh cnnection to theother machine?

Well, if it's a Unix system & you could get to a shell prompt, you might
be able to telnet back to Grex, log in, & chat.

Failing that, if I recall, the man pages on telnet may tell how to return
to a telnet prompt temporarily; from there you could do ! to get a shell
prompt on Grex.

And he's sorry he did, since he was shooting from the hip.
Thanks for a complete & informative answer.

Nothing like hearingthe exploits of the adventures of an explorer,
thanks popcorn!
  
Now, the next question is ... similar ... how to answer
a chat-help request when I've ftp'd to another site ....?
  

I use ^Z to suspend the ftp. Optionally bg to keep it running while I chat.
%ftp will resume it. (only works if you are running a job-control shell)

I was going to ask about ^Z to suspend the telnet, too. No go? I know
there are  programs, such as pine, that can't be suspended. Is telnet
one of those? Is there a telnet -z, so it can be?

I know that TinyFugue (tf) can do just a plain old telnet, and it's
a bit easier to control.  You can use the '/' key to send a command
to tf rather than to the system you're connected to, and there might
be a way to shell out of it, but I haven't explored the possibilities.

Re #10 and #11:  That's right, telnet passes ^Z through to the host
system, so ^Z doesn't work for suspending telnet itself.  On the Unix
telnet clients I've used, the way to suspend telnet is to type the
telnet escape character (usually ^]), which takes you to the "telnet>'
prompt; then type  z  to suspend telnet.

(By golly, so it is.  Maybe Picospan needs "check-redundancy" command
at the "Respond or pass" prompt that checks previously read responses
and tells you if the content of the response you're thinking of
posting has already been entered.  :-)

Some of us would never get to say *anything*.

Tried the various assembledges of commands listed above.
How do they work? Just fine! Thankxx.

Here's a slight variation on the question (asked of me by a user): 
The user dialed into a VAX (VMS) host and telnetted to Grex. While
connected, he got a "phone" request from the VAX host (like a write
request). How can he reply to the "phone" call without dropping
the Grex telnet session?
 

Does VMS telnet allow an escape character and either shell escape or suspend?
I'd presume it would work much like Unix telnet, but I have no experience
to back me up.

The person would need to be in a possition to send commands to the system
they recieved the request on.
If A person is recieving a 'phone' request on a Vax machine, but is
in telnet to Grex, they need to escape back to their command prompt
on the Vax machine in order to answer the request.

And what would be the command for that, without dropping the telnet?

I thought we already talked about this...use your telnet escape 
character to get the telnet> prompt.  Type 'help' to see all the
neat things you can do.  You could suspend your telnet session, too.

What is the telnet escape character on a VMS/VAX machine?

Ask thou system administrator.

That, or some kind of manual, is the only (more-or-less) guaranteed solution.
With the version of telnet we've got *here*, if you just run telnet but
don't connect to anything, and then issue the   status   command, it will
tell you what your escape character is.  But there's no guarantee that this
will work with telnet-type programs on other platforms.

As was said earlier, the standard escape character for the unix telnet
client is ^[. It can be configured with the "set escape" command.

No one here seems to know if it's the same for a VAX/VMS telnet client.
It may not be, but the documentation will probably show how to configure it.

Actually, the stanard escape character is ^].  ^[ would cause problems
for Vi users, and function keys on most terminals.

Ooops. wrong bracket.

The telnet on the VMS system at my university doesn't do that,though.
A quick browse through the help menus didn't clarify things either.

I'm a reluctant VMS user -- the machine that's used for some of the
classes I teach runs VMS -- and avoid learning more than what's
necessary.  However, I *think* it's possible to background things
on VMS, but I can't tell you exactly how.  I know that you can
start a task, suspend it to do something else (equivalent of Unix's
ctrl-Z), then resume it later.  I do that all the time to switch 
between editing and compiling.  Dunno how to run the suspended task
in the background, though.

I can run jobs in batch on the VMS system at work, but they have to be
submitted as batch jobs, and are processed on a batch queue.
This doesn't sound like it would be compatible with sending
a suspended foreground task into the background like you can on unix.
