Modem Connection Problems
You may encounter the following problems when using a modem. Additional
troubleshooting information is available in the Connections online help on the Pocket
PC and in the ActiveSync online help on the desktop computer.
Can’t Dial Out
• Remove your Pocket PC from the cradle. You cannot connect using a modem if
your Pocket PC has an active connection with the desktop computer.
• Verify that the modem is firmly seated and connected to your Pocket PC and the
telephone jack.
• Make sure the telephone line is analog. (Analog telephone lines transmit data in
analog instead of digital form. Your home telephone line is most likely analog,
while office telephone lines are often digital.)
• If you create a modem connection for an external modem, select Hayes
Compatible on COM1 as your modem. If you are using a modem card, select the
modem card as your modem.
• To use an external modem, you need to use a NULL modem cable and appropriate
adapters to connect the external modem to your Pocket PC.
• Make sure the modem is waiting for a dial tone. Tap
and then Settings. On the
Connections tab, tap Modem. Tap your connection and tap Next twice. Make sure
Wait for dial tone before dialing is selected.
• For international calls, allow more time for the call to go through. Tap
and then
Settings . On the Connections tab, tap Modem. Tap your connection and tap Next
twice. Clear Cancel the call if not connected within or increase the number of
seconds allowed. For information on dialing patterns, see Connections Help on the
Pocket PC.
Can Dial Out but Cannot Make a Proper Connection
• Make sure the network to which you are trying to connect supports the Point-to-
Point Protocol (PPP). Your Internet service provider or network administrator can
verify this.
• Verify that the location is correct. Tap
and then Settings. On the Connections
tab, tap Modem. On the Dialing tab, make sure that Location reflects your current
location. Tap Dialing Patterns to make sure the correct sequence of numbers is
being dialed. For information on dialing patterns, see Connections Help on the
Pocket PC.
