Troubleshooting
Problem Action
My modem application does not
work with the PC Card modem.
If the PC Card Director shows the PC Card modem status “Ready,” add
the following option switch in the CONFIG.SYS file:
For DOS:
DEVICE=C:\THINKPAD\IBMDSS14.SYS /IO =x (or /IO1=x)
For OS/2:
DEVICE=C:\THINKPAD\IBM2SS14.SYS /IO =x (or /IO1=x)
Note:
x
shows the PC Card slot number (1 for upper slot, 2 for lower
slot, or 12 for both slots) on the computer and “/IO1=” shows the slot
number for a docking station or port replicator that is attached to the
computer.
My PC Card modem does not
work.
Your computer is equipped with a built-in Mwave modem. If you want to
use the PC Card modem instead of the Mwave modem, you need to
release a communications port (COM port) for the PC Card modem. Do
the following:
For OS/2 or Windows
, start the ThinkPad Features program and
release a COM port for your PC Card modem by:
– Disabling the infrared device by clicking on the
Infrared (
) icon.
– Disabling the internal modem by clicking on the
Modem (
) icon.
– Changing the COM port for the internal modem from COM2 to
COM1.
See page 35 to use the ThinkPad Features program.
For DOS
, use the PS2 command to disable the telephony function or
infrared port and to release a COM port for the PC Card modem.
For more information or the latest tips, refer to:
– PC Card problems on page 254
– READ.ME file and PCMCIA.CRD file in the THINKPAD
subdirectory of the computer
I cannot use PC Cards other than
IBM ones in the OS/2 Warp
environment.
If you do not have the PC Card device driver for OS/2 but you have one
for DOS, your PC Card may run in the VDM (virtual DOS machine)
environment. Refer to “Virtual Card Services for OS/2” on page 290 for
setting the VDM and the sample configuration files on the PC Card
Director Diskette for OS/2 and Windows 95. (If the PC Card Director
Diskette for OS/2 and Windows 95 did not come with the computer, create
it using the Diskette Factory program.)
