If the ISDN modem is connected to a serial port, yes, the serial port
driver. Now, to my knowledge (but my ISDN knowledge is limited), there
is a high-level ISDN driver which is always the same for any ISDN
internal card (and emulates e.g. AT commands for modem).

Now, for the low-level hardware, it's a bit like Ethernet: each
hardware, be it passive (manually handled), or active (internal
firmware handling the details) has its own driver.

How is this handled, e.g. on the proprietary MS-WINDOWS environment ?
Do you have one (manufacturer-supplied) low-level driver ?  In my
experience, it often happens that there is only one good driver
for some hardware on Linux (e.g. the sym53c8xx driver supports all
sym53c8xx chips, be them on a Tekram, ATTO, LSI Logic or whatever
board efficiently, where proprietary MS-WINDOWS drivers are
a multitude, and are incompatible).

So, for me this means that it would be surprising the proprietary MS-WINDOWS
having one driver only and Linux with many drivers. However, you can't exclude
it.

It's a bit difficult to know, but ISA always has its standard problems,
for example IRQ or I/O port conflicts. It could also be another
problem.
