SYMPTOM POSSIBLE REMEDY
• In general, IRQ4 belongs to COM1.
IRQ3 belongs to COM2. COM3 and
COM4 can be set to IRQ5-7, 10-12, or
11-15. It is best to put an interrupt-
driven device on COM1 or 2 (e.g., a
mouse).
• The IRQ settings in your software must
match the settings in Windows 95
Device Manager.
• Verify that the external device is
capable of those speeds.
• Make sure the board is set to high-
speed mode with the J12 jumper.
• The settings must be set correctly with
the J12 jumper and Windows 95 Device
Manager. These settings must not
conflict with any other hardware.
• The diagnostics program used must be
capable of testing 650 UARTS. Most
diagnostics programs can test only 450
and 550 UARTs.
