1. General
==========
This document will point out some general essentials and advice on
setting up your modem. A section at the end discusses specifics
regarding a DOS setup running the KA9Q NET.EXE program. Due to the vast
combinations of computer and modem setups it is impossible to give
specific help for all types.
Making an Internet (IP - Internet Protocol) connection via a modem is
very different from a standard dial-up connection. Do not assume that
just because you can download from a BBS (and maybe upload) that you have
your communication (comms) set-up 100% sorted out. Due to the nature of
IP, if you get errors, throughput can be hit very badly. Under IP
information is sent in packets and for maximum speed these should
generally be as large as possible up to a maximum of about 1500
characters. If a packet gets messed up (garbled) its entire contents
will have to be resent - hence a large speed degradation may occur.
One exception to this is when an interactive sessions are sharing a
TCP/IP link with more voluminous transfers such as NNTP or SMTP. In this
case it can be preferable to have smaller transmission units (Maximum
Transmission Units setting or MTU) so that keystrokes/screen updates will
fit into the data stream with less delay. If a large MTU is used this
can lead to what feels like a jerky or intermittent session.
Enough of the technical parts, there follows some sound advice that
everybody should take note of.
2. Essentials
=============
Correct modem settings: full hardware handshaking (CTS/RTS),
flow control, XON/XOFF set to off, settings must be bi-
directional where appropriate.
A full specification modem cable (open yours up - if it has
only 3 wires it is no good).
A serial chip that can cope with the high speeds (if using a
high speed modem). Extended memory drivers and Terminate Stay
Residents (TSRs) etc. can interfere with the handling of
interrupts from serial chips.
3. Telephone Exchange
=====================
The Demon Internet Service (DIS) is on modern digital exchanges
so you should have little trouble with ringing tones etc when
connecting to us. If you are on an older exchange, your modem
may not recognise the dialling tone. If this happens, look in
your manual and change the setting that overrides the dial tone
recognition.
Note that when you make changes to a modem's settings you
should always reset the modem first, make the change and then
save the settings. You will need a comms or "terminal
emulation" package such as Telix, Procomm, Window's Terminal, Z-
Term, Microphone etc. Look in your modem manual for
instructions. Mostly you will be able to type ATZ <return> to
reset your modem. On a US Robotics/Miracom modem you could
type:
ATZ Reset the modem
ATX3 Alter a setting
AT&W Write the settings to Non-Volatile RAM (NVRAM)
The last bit (AT&W) is useful as it means that when the modem
is reset, it will remember the settings you have stored.
If going through a private telephone network (or PABX) first,
you will probably need to dial a number such as 9 to get an
outside line. Make sure your dial string has this in. You may
need to separate this from the number to dial by a separator
such as a comma so that there is a pause to give your telephone
system time to give you an outside line:
9,0813434848
4. Internal Modems
==================
Internal modems have the advantage of not having a serial lead
to worry about but the disadvantage of using an extra interrupt
and generally don't have any lights to let you know what is
going on. Ensure that the interrupt on which the modem sits
does not interfere with any others - refer to the setup program
for your computer and your modem manual. This may require
altering a jumper (a small connector) on the main computer
board (mother board) on your computer or on a separate board.
This should be well documented and is well within the scope of
the average user. Ensure that the modem is seated correctly in
the expansion slot.
5. Which Phone Number
=====================
We have multiple Points of Presence (PoPs) - please see
/pub/doc/Demon.txt for details. Thus you will have a choice of
numbers to ring. You may use any of our PoPs at any time.
6. Modem and Telephone Leads
============================
Your modem lead should be in good condition and preferably not
wrapped in a tight circle or running parallel to high power
cables etc. This will normally only affect longer runs and, as
your cable should be earthed, will not often be a problem. The
cable should be connected securely at both ends as should the
telephone cable. If you suspect your telephone socket may be
causing a problem then test it with a standard plug in
telephone. Use the correct type of modem lead - they vary from
country to country.
7. Serial Chips
===============
The type of serial chip (Universal Asynchronous
Receiver/Transmitter - UART) in use can make a big difference
to comms performance/reliability. At higher speed the computer
can sometimes not service the serial chip fast enough to catch
all of the characters arriving down the line. This problem
increases if running under a multi-tasker such as Windows,
certain memory managers and other TSRs.
8. Speed
========
Close to every modem user's heart is the speed at which they
can operate. There are two different speeds: the first is the
speed at which a modem can talk to another modem; the second is
the speed at which the modem can talk to its controlling
computer (the DTE rate).
Firstly, we will discuss the connect rate. A V.22bis modem can
connect at a speed of 2,400 bits per second. There are 8 bits
in a byte (a byte is usually one character) so that is a
maximum of 300 characters per second (cps). Due to start and
stop bits, each byte will take 10 bits reducing the speed to
240 characters per second. When running over IP there is a
slight overhead and so you will never see this maximum.
However, as you can (and will) have several things happening at
once, you will be able to make very good use of your available
bandwidth.
Many modems have compression protocols built in to them. MNP/4
and V42 use synchronous connections to provide an error free
connection between modems, saving the start and stop bits.
This gives at least a 20% increase in throughput. V42bis adds
compression, provided that the DTE rate is higher than the
connection rate. This means that when downloading a plain text
(or ASCII) file, it is possible to get faster speeds by
compressing the data. The data is compressed so that the same
information can be encoded in to a smaller space. The
receiving modem will of course unscramble the data for you. If
news normally flows in at say 200 cps, then, on a 2400 cps
link, you have up to 44 cps left at the same time for mail,
telnet'ing, ftp'ing etc. Compression techniques do not work as
effectively on binary files and make very little difference to
pre compressed files (such as .zip, .zoo, .lha etc.).
Note that MNP5 will usually degrade throughput on an IP link
due to the packet based nature of it's compression method.
V42bis does not suffer this problem as it is capable of
optimising itself dependent on the type of data being
transferred.
Now we will discuss the second speed - the speed at which the
modem and computer communicate with each other. This is called
the Data Terminal Equipment (DTE) rate. If you have a slow
modem, e.g. a 2400 baud one without MNP or V42, then it will
probably only work correctly when talked to by the computer at
the same speed. For the facts on your particular modem and
computer you should refer to your manuals. On faster modems
you will only be able to take advantage of some of the
compression features by making the computer talk to the modem
at a faster speed than modem is talking to the remote modem
down the telephone line. Thus you should talk to a 9600 modem
at 19200 or even 38400. You should check the maximum speed at
which the serial port on your modem can talk and then set your
communication package to work at the highest mutually available
speed. Don't forget that without a buffered UART you are
unlikely to sustain reliable high speed comms above 9600 baud.
Please note that we only support modems capable of V22bis
(2400) and upwards. If you have a US Robotics/Miracom HST
modem, you may not get very good throughput in HST mode. In
practice HST mode is fine if FTP'ing from a site without
anything else happening (sending mail etc.) as it works fine in
one direction at a time only.
9. Trouble Shooting
====================
If you are getting garbled characters on the screen then
something is wrong! Garbled characters are often a sign of
mismatched speeds, lack of handshaking or a non-locked DTE
rate. If you get as far as the login prompt but no further
then make sure that your dialler script is working on 8 bit
standard comms: 8 bits, no parity, 1 stop bit. See
/pub/doc/Demon.txt for the full logon script details.
Having checked your setup according to the information above,
try reducing the speed at which the computer talks to the modem
(if using a high speed modem) until the connection works. If
you have to do this then either you are attempting to drive
your computer or your modem at too high a speed, or you have
other processes running which interfere with the correct
running of your serial communications (as per Serial Chips
above).
If you have finished your live session and log off you may
sometimes find that your phone line is not dropped. This can
result in an unwelcome phone bill! There are a number of
computer/software specific solutions to this problem and some
answers are given in /pub/doc/Support.faq which may have been
included in your installation. One thing to check on your
modem is that the setting that makes the phone line drop when
the computer tells the modem that it has finished, is on. The
computer uses the serial port and drops DTR (Data Terminal
Ready) and the modem spots this and hangs up the line. The
setting often &D2 and you should read the section below which
tells you how to set this. It is definitely &D2 for US
Robotics, SupraFax and Dowty Quattro modems.
There is a section below which specifically refers to problems
that may be encountered by PC users.
10. Software and Other Factors
==============================
By configuring your software correctly you can make significant
improvements to an under performing communications connection.
Things to check for include badly fragmented disks (run a disk
de-fragmenter such as Norton's Speed Disk), no disk cache, no
or insufficient buffering inside the software and unnecessary
checking protocols or indexing taking place. Refer to your
software's instructions for details on these.
11. Help for Specific Computers
===============================
Some extra comments for some operating systems which may be of use
follows.
11.1 IBM PC Compatibles running DOS
===================================
In addition to the above info there is some specific advice
below for those of you running DOS.
Some modems send back "OK" when sent ATZ (the reset command)
even though they are not ready. This means that the dialer
program will try to ring out even though the modem is not
ready. The effect is that you will see ATZ on the screen
followed by OK and then the program will not dial. Eventually
it will time out. To avoid this, send AT instead of ATZ in the
modem initialisation string.
Extended memory drivers can interfere with the correct
operation of your serial communications. If you suspect this,
rename your CONFIG.SYS and AUTOEXEC.BAT files and then reboot
your computer to see if the connection improves.
If you have a V.32bis 14,400 modem you will probably want to
talk to it at 38,400. Unless you have a suitable serial chip
then you will get errors and, as explained at the start of this
document, this can seriously impact the throughput. When
running NET.EXE you can type asystat at the net> prompt and
information about your serial comms will be printed to the
screen. The interesting parameter is the third one on the
second line, 'hw over'. This shows how many hardware overruns
(characters lost because they weren't fetched from the serial
chip in time) have occurred. These overruns are usually due to
lack of either a buffered UART or hardware handshaking.
As already stated, for maximum performance you will need to
have a buffered chip. For this you will need a 16550A - this
is the number that is written on the chip. The asystat command
will tell you if a 16550 is detected. Unfortunately, even top
manufacturers overlook this area so it is quite likely that
your chip is below par.
If in doubt, open up your computer and locate the serial chip.
If it is not a 16550 then it might need replacing. If you are
handy with a soldering iron you could replace it, but this is
not advisable unless you are really confident. If the chip is
socketed then it can be removed and a 16550 (costing about #16
- we sell them) be put in its place. If not then you could buy
an extra serial card with a 16550 already on it costing from
around #30 to #70 depending on the specification.
If you are using a standard serial port then the settings
offered for COM1, 2, 3 or 4 in the configuration program in
DIS.EXE will probably be fine. Otherwise you should refer to
your manuals and enter the appropriate IRQ number and I/O base
address.
If you install an extra serial card then be aware that if you
have, for example, a mouse on COM1 then you should not use COM3
for your modem using the default IRQ setting as they share the
same interrupt.
There is another factor that can impede throughput and that is
software overruns. Using the NET.EXE software, at the net>
prompt having just received some news or ftp'd a file, type
asystat and look at the figure before sw over. If this is not
0 then you are getting software overruns. To fix this,
increase the buffer size in the attach line near the top of
autoexec.net:
attach asy 0x3f8 4 ppp sl0 4096 1500 38400
Alter the 4096 in the above to be 8192, 12288 or higher until
the software overruns are cured.
11.2 OS/2
=========
If intending to run the DIS DOS software in an OS/2 2.x DOS
session you should get a copy of sio126c.exe and install the
communications driver in it before running DIS. sio126c.zip is
available on our ftp server or via our guest download account.
This is because the standard communications drivers do not pass
to DOS the buffering of your 16550A buffered serial chip.
12. Individual Modem Settings
=============================
12.1 Setting Up a US Robotics/Miracom Modem
===========================================
To set up your modem, use a standard communications package.
Type ATZ <RETURN> and see the response OK. Then continue to
make the settings. You can type ati4 <RETURN> and ati5 to see
what your current settings are. For connecting to Demon we
recommend the following:
B0 V.32bis modulation rather than HST
C1 Transmitter enabled
E1 Local echo ON
F1 Duplex OFF receiving system sends duplicate data
Q0 Result codes displayed
V1 Display result codes in verbal (not numerical) mode
&A3 Enable additional error control indicator
&B1 Serial port remains at fixed setting
&C1 Modem send CD (Carrier Detect) on connection
&D2 Terminal sends DTR (Data Terminal Ready)
&H1 Hardware CTS (Clear to Send) transmit data flow control
&I0 Received Data software flow control disabled
&K3 MNP 5 data compression disabled
&N0 Variable link speed negotiation
&R2 Received Data h/ware (RTS) flow controlled by computer
&S1 Data Set Ready (DSR) controlled by the computer
e.g. type AT&K3 <RETURN>. When done type AT&W <RETURN> to save
the settings to Non Volatile Ram (NVRAM) so that they are
remembered when the modem is reset.
Some US Robotics occasionally mistake a System X (and Y?)
ringing tone for a busy tone and hang up just as the Demon end
answers. Sticking a pause on the end of the dialling sequence
stops the modem's response long enough for the Demon end to
start its negotiating sequence. This means that the confusing
System X tone is ignored. If the Demon end is busy you just to
wait a bit longer for the BUSY string, but not as long as the
setting in S7. Add a pause by adding a comma to the end of the
string.
12.2 Supra modems
=================
Supra 14.4k fax modems need the ROM revision 1.70B (or later of
course).
Information providing features
Enable all CONNECT, PROTOCOL & COMPRESSION mesgs: s95=41
loudspeaker control (low volume, on until carrier): l1m1
Modem/PC signals
modems disconnects when DTR drops: &d2
DCD follows line carrier: &c1
Enable hardware flow control: &k3
Speed connection, reject bad lines
new models, only make LAPM Reliable connections: \n4
old models, make AutoReliable connections: \n3
Disable negotiation, make V42 (LAPM) connection: s48=0
connect at highest shared data rate: n1
Compression
new models, V.42bis (BTLZ) Enabled, (but not MNP): %C2
old models, enable data compression (BTLZ or MNP): s41=1
An initialisation string for this would be:
ats95=41 l1m1&d2&c1&k3 \\n4 s48=0 n1 %C2
^note the double '\' is needed if typing this
into some dialer programs
To put this into the modem's memory (NVRAM) type at&w
12.3 Yoriko modems
==================
Yorikos work OK with a simple AT&F&C1&D2 set-up.
12.4 Zoltrix
============
These are one of our user's settings for a Zoltrix v32bis
internal fax/modem. He writes:
With X4, W1 and V1, I've managed to configure it very nicely to
redial
if the line's are busy after only 5 seconds, report CONNECT,
PROTOCOL
CARRIER, and BUSY
The only bit I'm vaguely unsure about is, whether disabling
compression (%c0
on mine), disables v42bis also, as I really only want to knock
out MNP 5.
&Q9 I think attempts v42bis, falls back to LAP-M+v42, then to
normal.
An annoying feature is that at&v only digs out probably a
quarter of
the settings - the '\' and '%' commands don't feature; some of
them
appear extremely useful: %Q for instance purportedly reports
line signal
quality, and %L received signal level, which I reckon might be
relevant to
one recent spate of postings, and you can tune up v42bis with
others.
S86 stores a connection failure cause code.
OK
at&v

12.5 Zoom modems
================
To force a Zoom modem to talk at only one speed:
AT&Q6S37=11M0X3&K4
13. Testing
===========
To test out your setup you could try using ping. ping
gate.demon.co.uk whilst logged on directly to gate should
return a speed of about 270ms on a fast link down to 1000ms on
a slow link.
Try using ftp to ftp.demon.co.uk and downloading files from
/pub/test. There are files of varying contents that have also
been compressed in various ways. "empty" files are there so
that you can test the maximum throughput on blank data. "full"
files contain a thorough mix of characters and so little
compression by your modem will be possible. "regular" files are
a mixture - just like this document or a Usenet news message.
Each of these three have been compressed using popular methods
and so you can try working on the compressed files as well if
you like. Try uploading these files to
ftp.demon.co.uk:/incoming to test the link in that direction as
well.
Using a V.32bis modem, the maximum throughput you are likely to
get on a binary file is 1,600 cps. On an ASCII file the
maximum is about 2,800 cps.
14. Finally
