This would be for my job that has devices which are connected to dedicated phone lines and must communicate with a system ever 72 hours to continue to work properly.
If anyone is willing to help me out on this I would be willing to pay something.
now this could be a not so complex app, just as long as it works.
here are some steps I've seen which is without a db for the numbers. please consider this, Thank you
1. Employ the SerialPort control (System.IO.Ports.SerialPort).
2. Open each possible serial port and send an AT command to each port and wait for a response from the command -- this detects the port on which the modem is connected. Use this port for dialing.
3. Open the database, and read in a telephone number.
4. Use that number to dial and wait for connect. Connection will be either a change in state of DCD from false to true, or the "Connectxxx" output message from the modem.
5. Record the rusult to the database
6. Repeat steps 4 and 5 until all numbers have been dialed.
Then either email or print out no connects
Thank You
