If a PCMCIA modem is already configured when Linux boots, it may be incorrectly identified as an ordinary

built−in serial port. This is harmless, however, when the PCMCIA drivers take control of the modem, it will

be assigned a different device slot. It is best to either parse stab or use /dev/modem, rather than expecting

a PCMCIA modem to always have the same device assignment.

If you configure your kernel to load the basic Linux serial port driver as a module, you must edit

/etc/pcmcia/config to indicate that this module must be loaded. Edit the serial device entry to read:

device "serial_cs"

class "serial" module "misc/serial", "serial_cs"

Serial device parameters

The following parameters can be defined in serial.opts:

LINK

Specifies a path for a symbolic link to be created to the ``callout'' device (e.g.,

/dev/cua* for pre−2.2, or /dev/ttyS* for 2.2 kernels).

SERIAL_OPTS

Specifies options to be passed to the setserial command.

INITTAB

If specified, this will be used to construct an inittab entry for the device.

For example:

case "$ADDRESS" in

*,*,*,*)

LINK="/dev/modem"

SERIAL_OPTS=""

INITTAB="/sbin/getty"

Comments about specific cards

• The Uniden Data 2000 Wireless CDPD card has some special dialing strings for initiating SLIP and

PPP mode. For SLIP, use ``ATDT2''; for PPP, "ATDT0".
