#CIS Problems
11 messages in this thread
Don,
I've been having problems with CIS and 2400 baud that may coincide with
the new forum software that went online a while back. Maybe you can offer
some help.
I've been using 2400 baud since CIS equalized the cost with 1200 baud and
have had no problems until recently. As will happen at 2400 baud, I
occasionally get a short burst of noise characters, maybe 6 or 8. This has
never caused any problems before. However, now what happens is that after
these noise characters, the system (CIS?) apparently sends a ^P. On my screen
I see
something like "83/.';][P ^P". It is always a ^P, never anything else. This
really causes a problem when I am doing a RTN on the message base as it throws
me back to the function prompt and my reading of the threads is messed up.
As I seldom get noise at 1200 baud, I don't have the problem there. I have
tried 2 different term packages (Diga and Aterm6.1), differents Amigas,
different modems, and different phone lines. Same problem. I can, however,
call in thru a Telenet node and do not see the problem. But this costs more
and is slower. I am presently dialing directly into a CIS node in Houston TX.
I have talked with CIS people and they can offer no help. They said they
checked the system out and found no problems.
Can you (or anyone else reading this) offer any solutions? Thanks.

Greg,
I, and a few others are having exactly the same problems, althou I
don't always get the ^P, that also happens. I've been bugging NetWork about it
and they are supposedly checking things out here in Denver. One common point
amongst the rest of us who are experiencing the problem is that we are on
direct CIS 2400 baud lines and using CTS 2424ADH modems. 2 of us are here in
Denver, and one other is in New York City so it's apparently some sort of
problem with the new 2400 baud nodes (it's not the system software).
For all of us, it started up about a month ago. We all have the
problem ONLY on CIS direct lines, not on TynNet lines. Here in Denver, we have
2 2400 baud nodes, one is clean 99% of the time, the other one is dirty 99% of
the time…unfortunately, the poor modem is the only one you can dial
into…the other only becomes active when the first is full.
I'm going to pass your message on to NetWork as another example of the
problem. They'll eventualy figure out what's going on and fix it.
Don
Don,
It looks like we are all in the same boat as I too have a CTS2424ADH modem. I
have tried a friend's modem (also a CTS) and, of course, his did the same
thing.
Is it possible we are seeing some sort of 'buffer full' handshake problem as
I noticed that it only happens if I am dumping text at pretty much full speed?
Doesn't matter if I am dumping the message base or one of the DLs. However if I
just sit on a function prompt, I can sit there for 5 mins without seeing a
single noise character. If I do a text dump I get the noise burst every 10-15
secs. I also can download a 20K file on the same line and not get a single
error so it doesn't seem like your normal noisy line.C
As you said, I don't always get the ^P either. I guess I get it about 50% of
the time.

Greg,
Well…that's good news and bad news. Good news that the problem seems
confined to a specific brand of modem…bad news that we own them!
Actualy, the problem is probably not the modem itself…as you know, it
works just fine with other services (TymNet, local BBS's et al) and here in
Denver, if we are luck, and one of the nodes happens to fill up, we get
switched to a secondary 2400 baud node and that node is perfectly clean.
What it is looking more and more like is that somehow or other, the CIS
modem starts to fall back to a lower speed for some reason or other and then
picks back up to 2400 baud. It's not like I'm losing characters, but rather
that some characters are getting sent as garbage…the same thing that I've
seen happen at work if a terminal and computer port (on our UNIX machines) are
at different baud rates.
I've got a few ideas to test…I'll let you know if I find anything
out.

Don,
I called and talked with Tod at CTS this afternoon to discuss our our problem
to be find out if he had heard anything about it.
He was not aware of this specific problem but said he would call CIS and talk
with them about it. He has been hearing about some strange problems concerning
some new UDC (or UDS?) modems that CIS is testing. He also wonders if this
could be connected with problems in the MNP protocol that these new modems
apparently havY as an option.
Although I can not link the change directly with this problem, CIS recently
(the last month or so) switched to a new phone exchange (227 to 462). I don't
remember a direct connection, but the time frame is certainly similiar. Can I
assume that they also switched to new modems at the same time?
Tod said he would call me back as soon as he finds out something. When he
does, I'll pass it on.

GreG,
I'm experiencing exactly the same problems on one particular 2400 baud
node (DEM). Out of curiousity, what type of modem are you using (please don't
say CTS! The only people I know with this problem are using CTS modems).

Damn! It looks more and more like a CTS modem problem. Your symptoms are
identical to mine, Don, and Jim's. The weird thing is that it happens only on
CIS nodes and ONLY at 2400. Guess it's time to start looking for a new modem.
I missed the symptoms of this problem. If you describe them, I'll see if I see
the same thing on the Supra 2400.

Steve, I don't think we should blame the CTS modem. I've been using one on CIS
for many months now, and have not had a single problem at 2400 baud until CIS
changed my 2400 baud access node here in Boston. One of the problems is the
modem likes to hang up on CIS just as the carrier is coming on the line with
the message "NO CARRIER". It seems to be caused by the way CIS answers the
line. There appears to be a double line polarity reversal, which the modem
detects as a line disconnect and therefore hangs up. I can circumvent this
symptom by manually dialing the phone, waiting for the tone, and typing "ATD"
which means go off-hook without dialing a phone number.
Now the really annoying part is the last three weeks I have not been able to
use 2400 baud for a download. It works fine for co or message reading. I fact
I was using it for CTV for quite a while with no problem. But every time I try
to download, I get to about the 70K point and the whole thing just dies. I'm
using CIS-B protocol, by the way.
I think the download problem is a little bit nastier because I have noticed
that there are frequent network interruptions at 2400 baud, you see it as a
momentary delay in transmission, but the "NETWORK INTERRUPTION" message has
such a long timeout that you're not aware of the problems.
I hope you can get CIS to do something, as I get error-free downloads at 1200
baud with the CTS, and I can use the CTS at 2400 with other services without
any of these symptoms.
