Q: After installing Windows XP, there is often a problem that cannot be detected when the Modem is detected or when the connection is established using Modem. What is the reason?

A: This type of problem with Modem in Windows XP is common in conflict with another COM port. First you can open the "Add/Remove Hardware Wizard" to determine if Windows XP recognizes the COM port. If the wizard detects a COM port conflict, the modem and physical COM port may be configured to use the same COM number. If so, then you need to set the Modem to another unused COM port, or disable the physical COM port.

If you are using a duplicate COM port, right-click it and click “Uninstall”.

You can check the current IRQ and input/output settings of the Modem COM port, and then compare these settings with the recommended settings in the Modem manual. Consistent.
