Hello together!
Also trying to use Siemens MC35i for GPRS connection within an application on XP, but really don't know how to authenticate with PAP & Co.
But
1. I can't believe that there are no ready (free or commercial) components to use for that reason, because this modem seems to be very common.
2. it's seems to be possible under SuSE-Linux to make an GPRS connection over this modem with just entering the AT-INIT-string and username and passwort for authentication. This conntection then is mapped as normal network connection and you've got internet access from any application. Is that possible with any tool under Windows?
Can't believe that it is so hard to get an GPRS connection with the MC35i, can it?
I would be very happy for any tips (free or commercial) for getting GPRS connection with the Siemens MC35i.
Thanks in advance
Andreas

what this mean can implemented in mcu 8051? how about algorithm in TCP/IP stack, routine flowchart?

| TCP/IP stack is implemented in module. You only need to send the required server IP or URL and some other info to get connected to the internet and start exchanging data. It is quite easy.

For all of your Enfora gurus, I have an interesting question:
I am trying to use an MTGL device in a way that probably it was not intended for, nonetheless I think it should work but it does not.
I want to use the enfora box as a simple telnet terminal. That means for example I would like to use the TCP PAD command ATDT66.55.4.6/23 and have a two-way session with the telnet server. By two-way I mean that whatever I sent to the serial port it is sent to the telnet server and whatever the telnet server replies with shows up back on the serial port.
However it only works one cay - from MTGL to the telnet server, and NOT the other way around. I can not see the responses from the telnet server, but anything I sent to the serial port (after CONNECT of course) shows up at the telnet server. I have wireshark running on the telnet server-end and I can see clearly that my Enfora payload packets are being sent, then the telnet server replies back and I can clearly see those payload characters as well going back to my enfora EXCEPT the enfora box never sends them to the serial.
Here is a schematic:
Will this configuration work? I could not see why not but I am new with Enfora so may be I am missing some command to disable a "hidden" feature?
Thank you
