pcmcia modem problems

[Norm Scherer]

I have an old laptop that I want to use as a special purpose router.  My 
broadband will be down for a few months and my solar system needs to 
call home every so often to report production.  My plan is to connect 
the solar system 'gateway' to the laptop via a crossover ethernet cable 
and have the laptop connect to my dial-up isp periodically so it can 
report its condition and production.

One part is hanging this up.  I have a Zoom 2975L pcmcia "dual mode pc 
card faxmodem" that I have not been able to get running on freebsd.  I 
have found some previous conversations (in the archives) about this 
particular modem but they were all about problems, none had solutions.  
I have observed the same symptom others have seen, CIS too long and 
interrupt storm on irq11.

Does anyone have any special sauce that will make this modem work?

I am running "FreeBSD 7.2-RELEASE-p8" but could upgrade if I thought it 
would help.

Thanks for the help
