3. COM/PCMCIA/PRT
This option controls settings for serial and parallel ports and the PC card slot.
(a) Serial Port
Use this option to set the COM level, COM1 or COM2, for the serial port
and PC Card slot. The serial port interrupt level (IRQ) and I/O port base
address for each COM level is shown below:
NOTE: If the Serial Port COM level is set to the same level as the PC Card
COM setting, the PC Card COM setting automatically changes from
COM1 to COM2.
(b) PC Card Slot 1
Use this option to select PC Card slot usage:
PCMCIA
Others
NOTE: Only one PC Card Slot can be set to Others. For example, if PC
Card Slot 1 is set to Others and you also set PC Card Slot 2 to Others, PC
Card Slot 1 automatically changes to PCMCIA.
When Others is chosen, use the sub-window shown below to control the
modem COM Port and power.
Use the COM Port option to select the interrupt (IRQ)/COM level for the
Toshiba card modem: COM 1 or COM2 (default).
NOTE: If you change the PC Card COM setting to the same as the Serial
Port COM setting, the Serial Port COM setting changes to Not Used.
Use the Power option to turn the power to the modem on or off.
