ING message with the RING message which the modems return when they detect an incoming call. These programs usually interrupt the connection and try to receive the non-existing call. Disable the RINGING message with ATS42.6=1. Calling from an Extension / Blind Dial If your modem is connected to a large inhouse telephone system, it may be necessary to disable the modem's dial tone detection since many systems do not provide a standard dial tone. This is done by setting ATS41.4=1. Now the modem can initiate a dialing sequence without having detected a dial tone. Let the modem dial the outside line code which provides the regular dial tone to your extension and then wait for a moment before continuing the dial. To wait, insert the W character at the appropiate place in the dial string. The modem will wait for the number of seconds specified in the S-register S6. Example: ATS41.4=1DP9W1234567 In some systems, the dial tone is requested not by dialing a number as above, but by sending a flash signal. In this case, insert the exclamation mark (!) into the dialstring: ATS41.4=1DP!W1234567 19-2
