PC Card Problems
The PC Card does not work.
l Make sure that the PC Card is correctly seated.
l If the card requires an IRQ (interrupt request), make sure that there is
one available.
l The PC Card may be attempting to use a COM port in a manner that
conflicts with the COM port being used by another device. Try running
the SCU program to change the COM port setting. If your PC Card uses
COM1, set COM1 as
Disabled. If your PC Card uses COM3, set COM3
as Disabled. If your PC Card uses COM4, set COM4 at Disabled.
WARNING: COM3 is reserved for use by the touchscreen, do not disable it.
