STB WIND/X Video Card Interferes with COM4 Serial Port |
Q102923
The information in this article applies to:
- Microsoft Windows versions 3.1, 3.11
SUMMARY
According to STB Systems, Inc., the STB WIND/X video card may conflict with the address of the COM4 serial port (2E8h). This article contains an excerpt from the "WIND/X Video Card" user's manual that describes the problem and workarounds.
MORE INFORMATION
The following text is from page 1-4 of the STB "WIND/X Video Card" user's manual:
The WIND/X graphics controller chip uses the hex port address 46E8 for one of its extended register sets. When only the first 8 bits of this 16 bit address are decoded in any operation, the address appears as hex port address 2E8, which is a popular hex port address for a COM 4 serial port. This may result in an address conflict and prevent COM 4 from functioning or cause it to operate in an unpredictable manner. (e.g., Windows losing text, COM 4 locking up)
If you have a COM 4, or any other device in your system that you suspect uses the 2E8h address, consult the device documentation for alternate address selection/configuration.
