In Windows, open Phone and Modem options from Control Panel, select Modems, then properties, diagnostics, query modem. This will give you ATI3 , ATI4 command responses. Post the results here.

Also, to make the modem wait for response longer, change the S7=55 number in the initialization string to a higher number, such as S7=90 (90 seconds before it hangs up)
