Linux does not have modem "drivers".

In the kernel, modems are handled by the serial driver (drivers/serial/)
or some PCI/winmodem cruft that emulates a serial driver.

User-space handles the actual "profile" of the modem, e.g. what AT
commands it supports etc.

One or two people did it like that. That doesn't mean its the right
approach. You can run the modem stack in user space which is easier to
debug and nicer to work with and use ptys to provide the virtual serial
driver
