Hello,

Today I make some experiments with it.
I have Zaurus SL-C860 with CackoRom kernel 2.4.18...

I edit configuration. After inserting BT2000E CF card is loaded serial_cs
kernel module.
DMESG: ttyS03 at port 0xf60002f8 (irq = 39) is a 16C950/954

# hciattach 10 ttyS3 ericsson 115200
# hciconfig hci0 up
Can't init device hci0. Connection timed out(110)

I've tried several combination with hciattach command with speed from 9600 to 
460800, flow enabled/disabled but without success.

Do you have some idea?

Do you know right parameters for hciattach?

There are some more useful informations:

# ls -l /dev/ttyS3
crw-------    1 zaurus   root       4,  67 Apr 10 21:58 /dev/ttyS3

I have few more questions.
In dmesg I see: ttyS03... Why not ttyS3?

When I make"rmmod serial_cs"
I see in dmesg this: tty03 unloaded.
Why tty03 and not ttyS3?

I'am a little confused ;-)

This cards works now with bt2000e_cs.o but sometimes my Zaurus freezes when 
removing card...
