Operating under Windows Me/98
This section describes the procedure for using the board under
Windows Me/98 and lists a number of points to note.
Procedure
When using the board under Windows Me/98, the OS must be set to
recognize the I/O address and interrupt level used by the
COM-2(PC)F. In Windows Me/98, this is called hardware
installation. Use the following installation procedure.
Check the Current Settings
First, check the current settings. Check which interrupt levels are
available. If using in Compatible mode, also check which COM
ports (COM1 to COM4) are already set. The COM-2(PC)F cannot
be assigned to a COM port that is already set. The procedure for
checking is as follows.
- Check the interrupt level
1. Select [System] from [Control Panel] and open [Device
Manager].
2. Select the [Computer] folder and click [Properties].
3. Display the [Interrupt request(IRQ)] list and check which
interrupt levels are available.
- Check the ports
1. Select [System] from [Control Panel] and open [Device
Manager].
2. Double click on the [Ports (COM & LPT)], [Infrared], [Modem]
folder and check which ports are already set.
