 Troubleshooting
Symptom Charts/ Modem -  6 7
Modem cannot connect 
to remote access 
server or to ISP
1
Verify the phone number of the server. Dial the number 
using a telephone and listen for the “whistle” of a modem. 
2
Make sure the user has set up remote access for the server 
being contacted.
3
The user may need to create pauses while the number is being 
dialed. Insert a comma between parts of the number where a 
pause might be needed. For example, the following entries 
cause remote access to dial “9” to get an outside line and then 
pause before dialing the rest of the number:
9 ,   5 5 5 - 1 2 3 4
Modem is dropping its 
connection
1
International only: Use the Modem Country Selector utility to 
make sure the modem is set to the correct country.
2
Try another cable and phone jack.
3
The phone line may be too noisy to handle the higher modem 
speeds. Try connecting at a slower speed or use a generic CCL 
file. (If you are familiar with the CCL script language, you 
can edit the modem script to force a connection at a lower 
speed.) If the problem continues, contact the phone company 
to report the bad phone line.
4
Check if the user has call waiting on that phone line. With 
call waiting active, an incoming call can interrupt the 
connection. Disable call waiting using AT commands placed in 
the init string of the dialup application. Usually the string is 
* 7 0 .
5
There may be a problem with the server the user is 
connecting to. Servers sometimes develop problems that 
disconnect users without explanation. Try calling back later 
or use an alternate number if one is available. If the problem 
persists, contact the internet service provider.
6
Reseat the modem and internal modem cables.
7
Replace the modem.
