POSSIBLE SOLUTION
Answer your voice mail to restore your normal dial tone.
Enable the auto answer feature. In RapidComm's Terminal mode, type ATS0=1 and press
ENTER. NOTE: You need to enable auto answer before every session unless you alter your
software's initialization string to permanently enable auto answer.
Try placing the call again. The phone company routes calls differently each time. To
verify a valid phone connection, enter RapidComm's Terminal mode and type
ATX3DT8479855092 and press ENTER (the phone number is the U.S. Robotics BBS).
This string bypasses the dial tone, allowing a connection if the modem is functioning
properly.
Check http://x2.usr.com/connectnow for a list of ISPs that offer x2 technology.
Call your phone company to determine if this might be the problem. You can also run U.S.
Robotics' Line Test utility to determine if your phone line is x2 capable. Visit our Line
Test Web page at http://x2.usr.com/connectnow/linetest.html.
