          Use an AT command? Have a look at the docs for the modem or the
          manufacturer's docs for the modem's chipset.

              Great, a tiny dialer that asks the user to install th framework first. *lol*
              :))

                  Hi,

                  Sure (lots of examples in my book -- see below). However, the details
                  depend on what you want to do AFTER dialing. Do you want to connect with
                  another modem to send and receive data, or do you want to then pick up the
                  local telephone and talk, using the modem as an autodialer?

                  For example, if you send this command to the modem:

                  "ATD5551234 " & vbCr

                  The modem will dial and attempt to connect to another modem.

                  If you send the command:

                  "AT5551234; " & vbCr

                  The modem will dial, but will then return to command mode, without
                  attempting to connect.

                  Dick

                      ROFL

                      I didn't think about that...
