[Xen-users] pcmcia modem on ttyS1 can't be initiated in a Xen environment

[js <forums@xxxxxxx>]

Hi list,

I have a Vodafone Option globetrotter GSM card which works in my laptop,
but not in a XEN dom0.
I'm trying to get this card to work in a xen dom0

MY LAPTOP:

[I--] [  ] sys-kernel/gentoo-sources-2.6.19-r5 (2.6.19-r5)
[I--] [  ] sys-fs/udev-087-r1 (0)
[I--] [  ] sys-apps/pcmciautils-014-r1 (0)
[I--] [  ] virtual/pcmcia-2.6.13 (0)

When I plugin this card into my laptop (not running xen) I get following
output:

dmesg:

pccard: PCMCIA card inserted into slot 0

#pccardctl ident

#pccardctl status

  Subdevice 0 (function 0) bound to driver "serial_cs"

#setserial /dev/ttyS1
/dev/ttyS1, UART: 16550A, Port: 0x03f8, IRQ: 4

When I use minicom to connect to ttyS1 I get my AT command set. 
Conclusion: the pcmcia card works on my laptop.





MY XENserver:

I have Gentoo  installed on a Dell Poweredge 750 with A6 bios (latest).
And software installed:
[I--] [ ~] app-emulation/xen-3.0.2 (0)
[I--] [ ~] app-emulation/xen-tools-3.0.2-r4 (0)

[I--] [  ] virtual/pcmcia-2.6.13 (0)


When I plugin this card into my laptop (not running xen) I get following
output:

dmesg:

my xen boot options are very basic:

title  GNU/Linux Xen
root (hd0,1)
kernel /xen.gz dom0_mem=256M
module /vmlinuz0 root=/dev/sda5 xencons=tty

I tried changing xencons to none, tty, ....
I also tried to omit the xencons parameter, ...




How come that I can't seem to be able to connect to my ttyS1 port?
Why isn't the driver initiated like on my laptop although pccardctl
status says the device is bound to serial_cs?


Thanks in advance all,

Js
