IBM ThinkPad 755CX User's Guide
When a modem card is installed in the PC Card slot, the Auto
Configurator assigns interrupt request levels and I/O window from the
information in the following data file and tuple data of the modem
card:
[ ]
Starting from the first "Port1" line, the Auto Configurator tries to
assign the resources from I/O window X 3F8 and interrupt request
level 4 for the modem. If the Auto Configurator finds resources that
are not occupied by the system, it assigns them to the modem. If
I/O port address X 3F8 is already occupied by the system serial
port, Auto Configurator cannot assign the first "Port1" line
([Port1=3F8,IRQ=4]) to the modem. It would then try to assign the
next "Port1" line ([Port1=2F8,IRQ=3]) to the modem.
The CardID parameter is used to identify the modem card that does
not contain enough tuple data. If the Auto Configurator cannot
recognize the modem card installed into the PC Card slot, you must
add the modem card identification indicated in the level 1
version/product information tuple. The identification must be written
using up to five uppercase ASCII characters. If you want to display
this character string, use the DOS PC Card Utility (EZPLAY.EXE),
Windows PC Card Utility (EZPLAY.EXE), or OS/2 PC Card Utility
(EZPLAY2.EXE). The preceding example identifies the modem card
as "MD24X." Make sure that you include the character strings,
following "MODEM." When you use OS/2, you can include up to five
character strings, following "MODEM." The Windows PC Card Utility
allows you to automatically register the character string by selecting
the Register button on the Card Information screen.
When you do not need to use the Auto Configurator, add the
following line after the "CardID" parameter:
The Auto Configurator does not assign resources to the PC Card
when this line is added.
