the malfunctioned faulty components.
Software Causes and Solutions:
A. Smartio C104H/PCI Series board will check the line status (CTS) before
transmitting data if the RTS/CTS flow control feature is set to Enable in
the configuration or application program. Please refer to the Connection
Cable and Cable Wiring chapter for proper wiring and check the line
status of the suspected port using the diagnostic LED indicators on the
mini tester.
B. The board controlling application might not be correctly written
according to the corresponding API of the operating system. To verify the
problem, please run another existing and known good application or the
utilities provided by Moxa. Such as Pcomm Terminal emulator or
HyperTerminal under Windows NT and Windows 95/98.

which did not report its resources, has already claimed the interrupt used
by xxx. appears in the Event Log.
This indicates the MOXA board is found, but the IRQ is conflicting with
another adapter. Please check the PCI BIOS IRQ settings first and then select
an IRQ that is available.

MOXA Smartio/Industio series board!” appears in the Event Log.
