LV dial up

Hi all again,

Does anyone know how to use labview to dial up a connection to the internet
(or to a remote server) using a modem?
I have an application that may need to do this to periodically download data
from a remote site. I also have an application that must send text messages
to pagers.
any ideas?

Cheers
John

If it is a TCP/IP application, both Macintosh and Windows will
automatically dial up to your ISP when data is requested or sent over
TCP/IP. To use a modem to dial a pager number, send it the appropriate
AT commands (to the serial port if using a serial modem). For example,
to dial the numeric pager 555-5342 and leave the numeric message
555-1744:
ATDT 5555342,,,555*1744
ATH
If I remember correctly, this will dial with DTMF (touch-tone) the
number 5555342, wait for about 6 seconds (2 seconds per comma) then dial
555*1744 (the * leaves a space on most numeric pagers). Wait before
sending the ATH, I believe that it is the hangup command, though the
modem will probably time-out after 30 seconds or so anyway.

See http://www.pcia.com/wireres/protocol/links.htm and look for a copy of
the TAP protocol to page alphanumeric pagers.

You can log onto the example programs database and search for hyperterminal. There is a program there which emulates the windows Hyperterminal program. This is simply a terminal to communicate and dial modems.

I have central location with GPRS modem and PC. At remote location there are GPRS routers transparent to Modbus and Modbus device. For GPRS I have coorporate APN.

I make dial-up connection from PC to GPRS modem and I can ping remote locations. I want to make LabVIEW application to read data from remote locations. So, I have to encapsulate Modbus into TCP/IP. How to do that?

I don't have an answer to your question, but I would strongly suggest that you start a new thread rather than trying to resurrect a 7-year old thread which makes no mention of Modbus. Smiley Wink

The producer of GPRS router gave me the wrong information. They used UDP, no TCP/IP.

It's work.

Well, good to hear you were able to resolve the problem. It took them 10 months to get you an answer? Smiley Surprised
