Dell Latitude PCMCIA Modem help needed

Post by Carl Lippitt (Honeywe » Thu, 20 Apr 1995 04:00:00

I'm having problems:

is to be addressed as /dev/cua1 and has been setup as:
  setserial /dev/cua1 port 0x2f8 irq 3 uart 16450 etc...

now when I dip -t -v, and set the port to cua1, dip complains that it
can't open the device and bails....

  note: setserial /dev/cua1 port 0x2f8 irq 3 autoconfig
  returns an UNKNOWN uart type....Hmmmm

I'm guessing that 1) I need to know how to turn on the power to the PCMCIA
slot prior to siezing the port via dip, or 2) need additional device driver
for this funky hardware device....


I'm anxious to get SLIP working soon......


1. help: PCMCIA compilation on Dell Latitude CPi


        I am seeking helping with PCMCIA compilation under RH5.1 on a Dell
Latitude CPi notebook.

        The system was working fine with the both the initial kernel
(2.0.34-0.6 and 2.0.34-1).  The relavent hardwares are TI 1131 (PCMCIA
controller, which is i82365 compatible) and Megahertz CC/XJEM3288
ethernet+modem combo card.  When it was working, the /var/log/messages

kernel: options:  [cardbus]
kernel: Intel PCIP probe:
kernel: TI 1131 Cardbus at 0x3e0 ofs 0x00, mem 0x68000000, 2 sockets
kernel:         host opts [0]: [ring] [serial irq] [pci irq 11] [lat
32/176] [bus 32/34]
kernel:         host opts [1]: [ring] [serial irq] [pci irq 11] [lat
32/176] [bus 35/37]
kernel:         ISA irqs (scanned) = 3,4,10 status change on irq 10

cardmgr[250]: socket 0: Megahertz CC/XJEM3288 Ethernet + modem
cardmgr[250]: executing: 'insmod
named[271]: starting, named 4.9.6-REL Tue May 5 19:03:42 EDT 1998

cardmgr[250]:  executing: 'insmod
kernel: loading devide 'eth0'
kernel: eth0: smc91c94: port 0x300, irq 3, 10baseT port, hw_addr
cardmgr[250]: executing: '.network start eth0'

However, I needed to compile APM into the kernel (and PCMCIA modules), so
I decided to recompile the kernel.  I followed PCMCIA-HowTo, enabled all
the top-level devices (PPP/SLIP/PLIP/IPX, NO apple-talk), enabled the
default network options but disabled all the card-specific drivers.  I
        1) recompile the kernel, and modules,
        2) install the modules, reboot
        3) cd /usr/src/linux/pcmcia-cs-3.0.0
        4) make config (and accepted all the default value); make all;
make install
        5) reboot

However, the ethernet will NOT work at this point.  'lsmod' will report
that smc91c92_cs is loaded, but network is functional.

going back to /var/log/messages, it now reports:

cardmgr[269]: starting, version is 3.0.0
cardmgr[269]: no sockets found!
cardmgr[269]: exiting

so can someone tell me what am I missing?  Should I enable cardbus
(experimental support) in configuring PCMCIA?

any help is very much appreciated,
