Warner,
thanks for your help. I have the modem part of my Xircom CBEM56G
working, coming in via this card right now.
In addition to the lines that you indicated I also had to
re-initialize the cfcr register to 8 bit mode, after the initial tests
have passed. If I didn't do that, I got an error from the probe 0
test and the modem would not attach.
I've appended the complete patch to this mail. Please commit if you
like, so others can benefit.
Thanks again,
Georg.
