now using Debian with a 2.4 kernel
and lo and behold the only bit of hardware giving me trouble is the very same modem. I've actually partitioned a few gigs of space to run windows NT which, regretfully im using to write this.

This is what i've done so far:
got the source from intel, followed the usual, make clean....etc etc
no go so i followed the extra advice:

if the driver compiles but the script just wont work for you.
Here are the bare minimum steps to get your modem to work.

0. log in as root.
1. insmod -f Intel536.o (Intel536.ko for kernel 2.6)
2. you can start "hamregistry &" at this point if you wish.
3. rm /dev/536ep
4. mknod /dev/536ep c 240 1 (note "240" is the default, if it does not
work see what /proc/devices says 536ep's major number is)
5. ln -s /dev/536ep /dev/modem
6. start a comm application like minicom and use the modem.

On following step 1` i got :
you are tying to insert a non GPL module into the kernel, contact the, company only they can help you.

or somthing like that.

so i looked for another way
on anothers advice i modified the intel source. In the coredrv/coredrv.c file and the serialdrv/softserial.c file, there is the line:

MODULE_LICENSE("Proprietary");

i changed these two lines (for the purpose of learning only) to:

MODULE_LICENSE("GPL");

however it returned to me:
unresolved symbol put_tty_driver.

I've found the offending bit of code but cant figure out how to fix it, any help or an easier way would be very greatly recived.

I had this modem up and running under Fedora core 3.
