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 3Com BBS). This string
bypasses the dial tone, allowing a connection if the modem is
functioning properly.
Remove all devices between the modem and the phone jack it is using.
Make sure the phone cord you are using is no longer than 12 feet in
length. Use the phone cord included with your Sportster if possible.
Try using a different phone line. Make sure the phone line you are
using is an analog phone line. Using a digital phone line will damage
your modem.
