What kind of formatting would be required for a PIC
to logon to a dialup connection and send an E-mail
consisting of data to another E-mail address??

I think I can connect to the dialup and exchange
password and user name,  But how do I send an e-mail??

Any Ideas??

Thanks In Advance!!

Kevin, connect to a dialup server and exchange password
is just the entry of the tcp-ip that you need to deal
with in order to gain access to the system.

An e-mail is just a package you send to an user at a
specific IP.

Are you sure you can deal with the tcp-ip protocol in
first place?

what you can do is use a pc as email server (who handles tcp/ip and smtp)
and have the pic send the data to the pc. there has been a commercial
system discussed here not long ago which uses a similar approach. but it
seems not too complicated to do it yourself -- what you ultimately need on
the pc is an application that can send email (you can get various
ready-made modules for that, or do it yourself) and that receives data on
eg. the serial port from the pic.

if you install linux on the pc (or have an isp with a unix server and a
shell account), it gets even easier. linux has an application, sendmail,
which allows you to send email from the command line. if you can dial in
via modem to that box, you can log in as a user and just call sendmail.
that's something a pic is definitely up to (call in via modem, log on, call
sendmail, transmit data, log off, disconnect). any old 386 with some old
14.4k modems should be enough for such a linux email server.

Well, depending on the kind of connection you have, there are a couple
of different ways you could do it.

If you have the option of dialing up to a shell account (not all ISP's
still let you do this), then you could just use the unix "mail"
program.  This program is set up for use with shell scripting, etc. so
it would be pretty easy to send a message with it...   But for  details,
you'll have to look at the man page - I haven't used mail in a while.

If all you have is a standard tcp/ip conectiop via ppp, it's a little
harder.  The easiest way then would probably be to connect directly to
the mail server.  If you use smtp for your mail (you probably do) this
is done by opening a telnet session to port 25 of the mail server.  This
connects you to the "sendmail" program.  You can probably find detailed
documentation on how to use this program at http://www.sendmail.org, and some
basic information is available by typing "help" at the sendmail prompt.

Hope this helps,
Corey Drechsler

As I recall it looks like this:

telnet mailserv.xxx.yyy 25
mail from: spam_OUTkdcompTakeThisOuTspamgte.net
rcpt to: .....piclistKILLspamspam@spam@mitvma.mit.edu

that's all nice, but i guess by the point you have a telnet session running
over ppp and tcp/ip the rest is really simple... :)

how would you set up a telnet session with a pic (without dialing into a
shell account, because then you don't need telnet in the first place)?

Yes, don't forget that nature does complicated things in an
easy way, while we use to produce simple things by the most
possible complicated ways.  Expect a lot of work to achieve
the goal to send a simple "Hello World" via the 'net.

i guess in this case it was more the "nature" of the underlying op sys

i still think that for anybody who wants to do this, the easiest (and not
veryexpensive) way to do this may be to provide a real outdated pc (386,
486) with linux and a small number (>0 :) of modems and phone lines as mail
server with shell accounts. this one can then easily forward the messages
to a "real" isp via ppp & smtp.

Yes, that's where I got stuck when I tried to do it manually using
hyperterm
and my modem...
The reason I wrote this is that Kevin said

> Well,  The reason I felt I could was I have done it manually.

I don't feel like doing all the tcp/ip stuff manually or implement a
tcp/ip
stack and PPP/SLIP on a PIC (which I'm sure is possible as you can buy
'embedded
tcp/ip' and someone wrote a ping deamon for the PIC) but you never know,
there
_are_ cracks around (And real programmers type copy con program.exe...).

But maybe one could build a RS232 Y cable, connect it to two serial
ports of a
PC and a modem, log all RS232 traffic on one port and do a mail transfer
as
usual on another one using some standard OS (turn off compression etc.),
plaintext replace all mail relevant stuff and send everything from a PIC
to the
modem... (this one is _really_ ugly)

I'd use some old 386 board, a 20 meg harddisk or a floppy drive, and
linux.

where can you buy actual embedded (on a pic) tcp/ip? the only one i know
has some proprietary serial protocol driver on the pic, which then connects
to a pc with also the same proprietary serial protocol driver, and a tcp/ip
stack. but you need the pc... which, as you say, can be just as easily done
with a 386 and linux as a mail server.

how much of ppp and tcp/ip do you need for that?

Apart form the software(tcp/ip stack etc) how do you actually connect
the PIC to the network. i.e what electronics are required to implement a
10base2 or 10baseT interface if you don't use PPP/SLIP ?

There was this site (http://www.vermontlife.com/gary/) that had a PIC (I think)
rigged up to a Crystal CS8900, which is 10BaseT Embedded Ethernet controller.
I emailed the webmaster of vermontlife.com and asked what happened, no

If you don't already have an old PC or if space is paramount to you, try a
PC104. In the event you does not already know about it, a PC104 is a very
small (4" x 4") board with a complete PC in it (I mean, VGA, 2 serial ports,
1 paralell port, and so on).

I've never tried to buy a PC104 module before, and for answering your
question, I browsed a little. It seems that those PC104 modules are very
very expensive. Most of them are over $500. And we are talking about 486's
with 4Mb RAM here. Maybe that they are expensive because of high integration
or industrial specs.

Now that I think of it, you may be better off with some of the new MicroATX
developements. They are conventional PC motherboards with a very small form
factor. Most of them use the new PPGA (also known as Socket 370) Celeron
specification. The processor itself is inexpensive (less than $80) and
starts at 300Mhz. The motherboards runs for something under $100. Just add
some memory.
You can even add IDE flash disks (a 4Mb IDE Flash disk drive is in about
$75, 8Mb for about $110).

You can learn about the MicroATX motherboards at:

Not much, depending what performance you need.

1off quantities, probably about £340 for a 386, up to about £500 for a 586.

That has most of the interfaces you need built in, serial, parallel, IDE, a
Flash disk, VGA, ethernet etc etc etc.

There are plenty of protocol analysers that can do it easily, as the
HP4957 and others, it gives you all the data flow from both sides.

The problem is:

All the code is produced based on the protocol, and it is ruled by
protocol specifications that is a real time coded. It means that if
you understand the protocol, its control bytes, flow and counters
flags and so on, you can write the code "n" size, while just trying
to replicate the data flow, as you don't know how to build the
bytes, but instead you just need to have them stored in the code,
as a tape recorder, it can take "n" times 10 or more.

In the specification X.25 there are flow counters that make sure
about the block count, received and sent data blocks, as well,
control blocks, what will make the other side reject a wrong
numbered data or control block, so it would be quiet difficult
to stablish a "pre-recorded" protocol data to match the exactly
counters... they goes from zero to seven, but you need to match
both sides... one chance in 64 to make it works.

Also, the protocol is not a fixed thing, if the other side just
request a retransmition, when it was not recorded, sure crash.

Looks like if you record a phone conversation that was:
1) Hey, how are you doing?      2) very well, thanks and you?
1) fine, thanks, ready to go?   2) yes, you can pick me up.

Then, you record side one to simulate a live person, and call
number two, so you want to trick that person... and then:

1) Hey, how are you doing? (pre-recorded)
2) what? repeat please. (live)
1) fine, thanks, ready to go? (pre-recorded)
2) are you crazy or drunk? [hung-up] (live)

crash!


The best and esasier solution?  dig inside the IBM's books about
tcp/ip, hdlc, and 6 months later you will be an expert, at least
about sendind an email.  :)

Some time ago I saw an Internet Printer Adapter, something that looks
like its brother, the Ethernet Printer Adapter, but it is a little
bigger and was costing more than $100.
It was exposed at one electronic show at Orlando's Convention Center,
and it was to has a fixed IP.  But I can't find the supplier's name.

It could be a second option, after the use of a cheap 486 slc 25 running
Windows3.11... without monitor or keyboard, with a custom made interface
between serial port and the tcp/ip application.

I meant the Crystal CS8900 http://www.vermontlife.com/gary page...
As I got it the Crystal is an Ethernet (10BaseT) controller so he didn't use
PPP, just IP and UDP (I think ping is over UDP).
But I think it IS possible to do tcp/ip on a PIC. The question is, do you
really need it?

Of course you'd have to understand the protocol first - or you'll never
establish a valid connection, too much possibilities where you could
crash.
Let's have a look: Within the IP header you'd have to change total
length, identification, header checksum, fragment offset (?), MF (more
fragments) for each individual datagram...you're right, that's really
too much for plaintext replace!

Well, to be a doctor and write a simple medicine prescription
you need to go to college during 6 years, if you don't have
that time available, you pay to who already did it. :)

Yesterday somebody just asked me if I would like to teach him
all I know about computers in 2 weeks... The answer took half
an hour to say that it is impossible. He thinks I am bad.
He doesn't know what means "boot disk", and he calls a CD
"floppy".

I know all IBM comm. protocols, S/S BSC1,2,3, SDLC, HDLC, X.25
and Token Ring, worked with those during 15 years, and it took
me 45 days to write a simple 8051 assembler code (3kBytes) to
drive a printer with IrDa (high speed infrared), it uses a
modified HDLC protocol.

I don't know, probably you could be able to write this code
in just a week, and in this case I want you as my business
partner.  :)  would you like Florida?

I would wait few months, lots of companies are designing chip
sets to access the net. Philips just announced sometihng in
the area, and I would not be surprised if several routines
and protocols would be silicon driven.  If you think about
it, the World is open for this new hardware chips, isn't ?

sure. especially as there will be some time till you

The problem is: If the physical/data link layer is not 802.3 (Ethernet) you'd
have to do very much special code for every application (imagine IP over PPP:
there are many different ISP setups I think)

The World is open for these, but until you can handle these devices as
easily as a watch people aren't.

Two years ago some friends and me made a robot which you can control
over the Internet and applied to a competition ('Jugend forscht', a
german school related one) but most of the jurors didn't even understand
what our goal was.

It's not by incidence that example #1 of the FlatStack 'visions' is a
remote maintenance application.

Maybe in some months when I'm having school holidays I'll try to do an
embedded webserver with an Ethernet interface (given that there are no
simpler solutions available then).

As usual, I beg your pardon about my English. I don't live in 'America'.

Crystal its a filial of Cirrus. I don't remember exactly the url, but try it
at http://www.Cirrus.com, and browse a little.  The cs8900 has a *very good* set of
datasheets, in pdf, with board examples (& PCB drawings) o build an Ethernet
card, and a lot of code to download (C code), to create drivers. And the
best of all is that you *can* ask for a sample and they *really* send you.
Perfectly packed in a antistatic cover, etc. Very professional.

I only hope not to have raised the 'wild cs8900 free chip hunt' ;)

Keep on PICing
