Hi,
Does anyone has experienced email generation with PiC ? (protocol,
interfacing,...)
Thanks for your help.

Hi,
I am very interested in the protocol to connect to servers also.
I'd like a PIC to receive email also.

Thanks for any info,
Dave Celsnak

If you have a SMS to email gateway on your GSM network,
you can use a GSM modem. I've done it with a PIC, and
it is really easy. Contact me if you want info on modems.

Hi,

I think it is easy to do.  All you need is a Linux/UNIX server connected
to the internet.  Connect the PIC to the R232 port and simulate a telnet
to it and execute 'mail' command.  The software is easy to do because it
is only scripting (send and waitfor sequence only).  Honestly, I haven't
implemented it yet but it is very feasible.

regards,
Reggie

I think Pascal wanted a direct PIC to Internet connection.
Has anyone ported Linux to a PIC yet :-) ???

Thanks, I got your SMS (email). If your GSM network
operator has some sort of a sms-email gateway, you
can send email with some 3 or 4 command sent to the
GCom from your PIC.

So :
1) Contact your network operator and ask them if they
  know of a gateway for their SMS.
2) Look at the specs of the GCom on my page.
3) If 1) and 2) look good, then you can get pricing from

Actually this is overkill as you need to parse the messages in the PIC.
Middleware is required in the Linux box to convert email into a simple
delimited text and delimited simplified header, and back. The middleware
seems to be a Perl job. Then, the PIC only has to understand the
To: name (filtered already).

Hi,

For this application, the PIC needs a physical connection to the
internet.  A modem perhaps connecting to the ISP.  But instead of a PPP
connection, Pascal might just ask his ISP to have TTY telnet connection
directly (if ISP's server is UNIX).  Error connection may not be needed
because most modems have.

regards,
Reggie

Someone asked about a direct connection to the internet, suggesting
they either want a modem(ppp) connection or ethernet.  I should
say that to port even a small subset of tcp/ip to the PIC would
propably be a big enough undertaking (can you say zmodem?) that
it isn't the job for a pic.
Price is a bit steep, but if you need a real internet (telnet actually)
connection check out http://www.lantronix.com/.  They make some
single serial port terminal servers that work great for embedded components.
I use them for some pc applications (where tcp/ip is not supported
on the app but serial comm is)

check them out.

cummunicate with the main module into the House/building and the
external "Terminal".

After, my next extension was to make this system available for industry.
So need to check the validity of each key code, communicate the
date/time of each entry/exit of people, and so on and so on. Then my
idea was to make an ethernet connection to the intranet and then email
small messages to main system.

Yes I known, another solution is to keep RS232 connection to another
system, manage my own protocole, and manage Email with a LiNUX box, but
do not want to manage all this kind of stuff, even if it will funny to
make it.

Thanks for all your help.

A winner of the Circuit Cellar Ink & Microchip Design'98 contest
was an interesting "internet appliance". Quoting from the abstract:

"A PIC 12C672 handles all the tasks of dialing an ISP,
negotiating PPP & IP, authenticating itself with PAP,
finding its IP address, implementing PING protocol and
TFTP"

Try http://www.circuitcellar.com, may be there is some more info.

I was thinking along the same lines, but a little investigation revealed that:

1.  My ISP is using PPP, but not PAP.  That's makes a PIC dialup a little
easier.
2.  My ISP doesn't support TFTP.

Off hand, I'd guess that UDP might be doable on a PIC.  But I can't think
of any common UDP services that would be useful for transfering a moderate
amount of data.

Anyone got a workable idea?

That would depend on what they're using instead.  I don't think you want to
try to do MD5 (used for CHAP) on a PIC.

TFTP uses UDP.  TFTP *is* the common UDP service for transferring a modeate
amount of data.  It has no security of any sort, so it wouldn't be very
popular for ISPs...

Actually, it is more difficult to parse variable length data for expect
login scripts in a PIC, than fixed length PPP data structures negotiating
IP.

I am so surprised ;)

ICMP can transfer any data you wish using PING packets for example. Look
up the RFC that documents PING. Check out 'pad bytes' ;) All you need to
do is have a server support an ICMP daemon that can make sense of these
padded bytes and send other ones back.

> Anyone got a workable idea?

Is this workable enough ? BTW PING will be routed over WAN so the PING can
go to a server on the other side of the planet where the specialized
server listens for it. Linux comes to my mind as a candidate. And is all
that is needed to communicate really.

Also, TFTP need not be supported by 'your' ISP, it needs to be supported
by your peer on the Internet, who can be a dial-up user like you, although
someone may be anal enough to filter TFTP in a firewall on the way (if you
pardon my French), so PING is a better way.

BTW beware of pinging certain types of hosts with variable padded data ;)
They BSOD or such ;)

Check out the PIC12Cx "Internet Appliance" that implements PPP, PAP, ping,
TFTP and a bunch of other stuff all on a PIC12C672.

http://www.circuitcellar.com/Design98.htm

I assume that if that can be done POP3 and/or SMTP would be trivial given
the existance of some sort of TCP/IP stack.

POP3 and SMTP use the TCP protocol and the PIC based solution only does
UDP and ICMP.

I was looking around the internet and found a project with an apparent tcpip
stack
at http://www.geocities.com/SiliconValley/Way/5807/ under the interface
section.
I dont know if its already been mentioned.
