RS232 modem-side driver - does it exist ?

is there in Linux any kind of driver (or driver support infrastructure)
for the DCE end of a RS232 - basically, for running Linux inside a
modem-like device and driving its RS232 interface.
This means especially that the DCD (Data Carrier Detect) and RI (Ring
Indicator) lines must be *output* lines settable by software, not input
lines. It would be best if I could simply use the normal tty_ioctl(4)
interface for that.
I know that there's a concept of "gadget drivers" in the Linux-USB
infrastructure, for running Linux in an USB device. Is there such a
thing for RS232 as well? Or will I have to write my own?
Any help appreciated.
