Q3 How do I fix a serial port conflict?
Answer

A number of situations may result in serial port conflicts. Certain software applications will take over or reserve a number of COM ports. Others may rename COM ports without your knowledge. However, the most common conflicts occur when you try to connect PoinTech to a PC that is being used with other serial port devices, such as modems, personal data assistants, or writing tablet programs.

When a conflict arises and the PoinTech application indicates that it cannot connect to PoinTech, check the hardware cable connections, then use the Attach PoinTech Settings dialog box to test your COM port connections. When you test your COM ports you can receive one of three results for each COM port.
* PoinTech has been successfully located.
This message indicates PoinTech has been found and is communicating with the PoinTech application.

* Unable to detect PoinTech.
This message indicates the COM port is open and installed, but PoinTech is not connected to the port. If you receive this message, check to make sure the PoinTech serial cable is properly attached.

* Serial port could not be opened.
This message usually indicates that another device is using the serial port to which you connected the PoinTech. The most common example is a Personal Data Assistant which uses a docking device attached to a serial port.
