Chapter 4—Troubleshooting
Troubleshooting
This chapter covers common problems you may have with your modem
and how to solve them. Your MultiMobile was thoroughly tested at the
factory before shipping. If you are unable to connect successfully, or if
you experience data loss or garbled characters during connecting, it is
possible that the modem is defective. However, it is more likely that the
source of your problem lies elsewhere. Always make sure all hardware is
properly connected. Then review the common problems listed in this
chapter for recommendations on what to change. At the end of this
chapter are specific steps for resolving IRQ and COM port conflicts.
If you are unsuccessful after trying possible solutions listed here, call
Tech Support at 1-800-972-2439.
When running applications, the system reports “Open port
fail.”
• Make sure the PC Card is properly plugged into the PC Card slot.
—Windows 95 displays “Open port fail” because the MultiMobile is
in use by other applications. Terminate the other applications and
try again.
—If VCOMM API is used, make sure the application’s COM port
setting is consistent with the COM port setting in Windows 95’s
System properties.
—If all the above solutions do not help, uninstall the MultiMobile and
install again.
